World War II (1939–1945)

American veteran soldiers are entitled to several benefits as recognition for their service on behalf of the country, but this was not always the case. Before 1944, war veterans received pensions and disability-related medical care, but that was it. WWI veterans had received bonuses for their service, but these were not redeemable until 1945, which led to protests and turmoil during the Great Depression.

To avoid a similar situation with soldiers serving in WWII, a set of laws, popularly known as the "G.I. Bill", was passed in 1944. These laws guaranteed that, in addition to pensions and medical assistance, veterans were entitled to financial help towards education or training, low-cost loans, unemployment benefits, and job-search assistance . Since then, additional "G.I. Bills" have been passed, ensuring that veterans are looked after once their service is complete.

The Great Depression (1929–1939)

Historians agree that, despite President Roosevelt’s best efforts, the Great Depression was effectively ended by the industrial mobilization caused by WWII. America’s biggest economic crisis to date had been brought on by several factors , many of them related to reckless market speculation, inefficient monetary policies, lack of social security, and massive bank withdrawals made by panicked citizens.

While F.D.R.’s "New Deal" policies were insufficient to overcome the crisis, they successfully set up a system to prevent a similar economic collapse in the future . As a result of financial and banking reform, personal accounts were federally insured —which prevented future massive withdrawals that would deplete savings, commercial and investment banking were separated, and commissions were set up to regulate trading and prevent fraud. Additionally, social and welfare laws established pensions, work insurance, and unemployment compensation, and protected unions that allowed workers to collectively bargain with their employers.

The Great Chicago Fire (1871)

On October 8, 1871, a fire started on DeKoven Street, Chicago, and it burned for three days, destroying 17,450 buildings and leaving 300 casualties and thousands of people homeless. According to legend, the fire was started by a cow (owned by a woman named Mrs. O’Leary), although this was never confirmed; it was the wooden buildings, the strong wind, and the dry weather that turned an accident into a catastrophe.

Americans from all over the country rallied behind the relief effort, donating money, food, clothing, and more, but the tragedy also forced authorities to review their own municipal safety codes. New fire and building safety codes were implemented, banning wood buildings and requiring fire-safe materials such as brick, stone, or marble, as well as fireproof staircases, exit signs, and outward-opening doors. A new fire academy was founded to properly train firefighters, which put Chicago at the lead of America’s firefighting force.

Yellow Fever (1793)

In 1793, the city of Philadelphia received cargo ships from Saint-Domingue (modern-day Haiti), and with them, an epidemic that lasted for half a year. Among the cargo from the Caribbean, there were yellow fever-carrying mosquitoes, which thrived in the crowded docks and in the humid spring and summer weather. The open sewers, poor waste management, and general ignorance about the disease worsened the situation, which only let up with the cold fall weather, with 5,000 people, about 10% of the population, as casualties.

Although the widely believed cause of the spread of the epidemic —foul "miasma" or bad air— was incorrect, it did lead to proper infrastructure changes to prevent a similar situation. The city targeted polluted waterways and rotten waste, exposing severely contaminated wells. Municipal water systems to provide clean drinking water were created, and paved streets with proper gutters and sewers reduced the amount of stagnant water . Additionally, the crisis led to the establishment of municipal health boards, proper quarantine facilities for incoming ships, and municipal hospitals all across the country.

The Triangle Shirtwaist Factory Fire (1911)

Nowadays we expect any factory or building to have proper fire and safety systems in place, but not so long ago safe working conditions were not a given. Places like the Triangle Shirtwaist Factory in New York not only lacked fire alarms, sprinklers, and fire escapes, but also locked their doors during work hours to prevent unauthorized breaks and workers' union gatherings . On March 25, 1911, when a pile of rags caught fire, the single fire escape collapsed and, with firefighters' ladders only able to reach six of the ten floors, the factory became a deadly trap that took the lives of 146 workers.

New Yorkers were outraged by the conditions that led to the tragedy, and public pressure led to the establishment of an investigating commission. As a result, more than 30 safety laws were passed , making fire drills, sprinklers, fire escapes, and emergency exits mandatory, among other measures, all of which set a precedent for federal safety codes and protections. The event also strengthened labor unions all across the country, who pushed for better working conditions.

The Dust Bowl (1930s)

The 1929 Wall Street Crash had already kickstarted the Great Depression, but the American crisis was still deepening. By the start of the 1930s, years of severe drought had hit the Great Plains (comprising ten states in the Midwest and Rocky Mountain regions) and had worsened an environment already depleted by human intervention. Native grasses that protected the topsoil had been eradicated through plowing, leaving the land vulnerable to wind erosion, while intensive cultivation of single crops had depleted the land. All this caused severe dust storms that hit the plains, further eroding the fields and suffocating the crops. In an agricultural recession, thousands of families migrated West looking for work.

The government’s response had diverse approaches. The Soil Conservation Service focused on changing detrimental agricultural practices through educating farmers on contour plowing, crop rotation, and shelterbelt tree planting. FDR’s "New Deal" plan established subsidies for farmers, requiring landowners to distribute a percentage of the subsidy to their laborers, and thousands of cattle were acquired, butchered, and distributed by the government to the affected population. Ultimately, the return of rain in the 1940s ended the drought and helped restore the soil, but the education, conservation, and relief mechanisms implemented by the government ensured that the Great Plains would not be as severely affected by drought in the future.

The Cold War (1945-1991)

The euphoria of the WWII victory in American politics was short-lived, as the climate quickly shifted to a new threat: communism. The Cold War deeply affected domestic American life, and the paranoia of the Red Scare prompted the government to invest thousands of dollars in defense , infrastructure, political propaganda, and counter-espionage. Sadly, this paranoia also allowed government officials and politicians, like Senator Joseph McCarthy, to persecute and blacklist thousands of suspected communist sympathizers without solid evidence.

While the desire to beat the USSR in public achievements resulted in the government funding the military industry, science education and research, and sports programs, espionage and propaganda were targeted through the creation of federal agencies —among them the CIA, the NSC, and the NSA— that managed domestic security, international intelligence, information, and propaganda.

The Revolutionary War Smallpox Epidemic (1775–1782)

The 1775 North American Smallpox epidemic lasted for nearly a decade, well beyond the Revolutionary War, but the military leaders of the Revolution were the ones to put in the efforts to contain it and prevent further spreading of the disease. In 1775, smallpox was a rampant disease in the American colonies, and a big part of the population had not been exposed to it due to isolation. This meant that, when colonists from rural areas joined the Continental Army, overcrowded military camps became a hotspot of contagion. It is estimated that smallpox caused more casualties than the fighting itself.

While smallpox decimated the Revolutionary Army, the British, who had been traditionally exposed to the disease, were immune to it. Recognizing the need to stop the spread of the disease, George Washington ordered a secret mass immunization of the troops in 1777 , a measure that drastically lowered the mortality rates among the army. While several founding fathers were in favor of mass inoculations and better public health policies, most of the colonists were distrustful of vaccinations and of government-mandated health policies. The success of Washington’s mass inoculation showed that public health policies could make the difference, and paved the way for later policies and health systems.

The Cholera Waves (1832–1866)

The U.S. went through three major cholera waves in 1832, 1849, and 1866, with tens of thousands of casualties, economic crises, and mass panic. Rapidly growing cities lacked proper sewage, and rancid water accumulated in the unpaved streets, while overcrowding and poor living conditions furthered the contagion. New travel methods such as the railroad helped introduce the disease to different regions, while doctors blamed the epidemic on "bad air" or a divine punishment.

It was not until the 1866 wave that city governments decided to change their approach to the health crisis. New York was the first city to establish a Metropolitan Board of Health, which focused on improving sanitary conditions and reforming the hospital system. Police forces encouraged (or forced) residents to clean their yards and remove manure and rotten waste, while the city strived to maintain clean streets and build sewage systems. By the time the third cholera wave hit New York, the city was prepared, and the number of casualties was much lower. Following its example, other major cities established their own permanent boards of health, implemented municipal health codes, improved their hospitals, and constructed underground sewers.

The Smoking and Lung Cancer Crisis (1960s)

Although tobacco had been popular for decades, the 20th century saw a rise in consumption thanks to aggressive cigarette marketing campaigns in print, radio and television. Smoking was allowed everywhere, and it was portrayed as stylish and smart in movies and magazines. There was a lack of education about the addictive properties of nicotine and the chemicals present in commercial cigarettes , a fact that the tobacco industry was eager to keep concealed. By the 1960s, lung cancer and heart disease numbers had risen dramatically, forcing the government to address the situation.

The 1964 Surgeon General’s report was the first to publicly link lung cancer and heart disease with tobacco consumption. Following several reports by other specialists , public opinion about cigarettes drastically shifted, despite the efforts of the tobacco industry . In 1965, Congress passed a law requiring mandatory health warning labels on cigarette packaging, and in 1971, cigarette radio and TV ads were outlawed. As a result, from the 1960s to the 2010s, cigarette consumption decreased by nearly 50%.

The Pure Food and Drugs Act (1906)

If you are the kind of person who religiously scans the ingredient list on food and medicine labels, you might not know that these labels exist thanks to a novel (and several journalists' investigations). In the late 19th century, increased food and medicine demands led manufacturers to sell tainted or unsafe products with false labels and filled with unsafe preservatives. Factory sanitary conditions were also subpar, which led many journalists to write about the issue. In 1906, Upton Sinclair’s novel The Jungle described the meat-packing industry practices in a graphic and revolting way, which caused mass outrage.

The Pure Food and Drugs Act of 1906 was the first of a series of laws passed by Congress to address the issue. It created a federal agency (now called the FDA) responsible for overseeing food and drug manufacturing , banned a series of commonly used substances and active ingredients, outlawed the sale of spoiled or contaminated food, set an inspection system for factories, and acted as a baseline for future consumer protection laws.

Spotted and striped cucumber beetles

Striped and spotted cucumber beetles favor cucumbers and melon vines. These insects spread bacterial wilt from plant to plant, a disease that is often fatal. When striped cucumber beetles are a chronic problem, the best course of action is to choose bacterial-wilt-resistant cucumber varieties .

2

Colorado potato beetle

Image: Олександр К

As the name implies, the surest way to attract Colorado potato beetles to your garden is by planting potatoes. These insects lay clusters of orange-yellow eggs on the undersides of leaves, which hatch into highly destructive orange larvae that feed voraciously and grow quickly. While beetles can be killed at any stage, it's easiest to remove the adults and eggs by hand .

3

Eggplant flea beetle

Image: Weronika Romanowska

Eggplant flea beetles can destroy an eggplant plant in just a few days. While many insecticides can kill these pests, the most effective method requires protecting plants with summer-weight floating row covers. These covers transmit enough sunlight while physically blocking the beetles from the plants.

4

Harlequin cabbage bug

Image: David Clode

These insects might look striking, but they are the worst enemy of summer kale, broccoli, and other brassicas. They suck the sap from leaves, leaving behind unsightly pockmarks.

Harlequin cabbage bugs can be picked off by hand , and wearing a face mask can help you avoid the unpleasant odor they emit. Also, spraying them off with a jet of water will help knock them back.

5

Mexican bean beetle

Image: Viktor Talashuk

In a similar case to the one we mentioned earlier, it’s the larvae of Mexican bean beetles that cause the most damage. The adults emerge in late spring but usually don’t become a serious problem on bean plants until midsummer.

The best way to deal with this pest may seem harsh, but necessary if you want to keep your other plants safe: you must completely harvest and remove the infested plants from the garden . After picking all the beans, the entire plant should be pulled, bagged, and taken far away from the garden.

6

Red spider mites

Image: adege

Tiny red spider mites live on the undersides of leaves, where they feed on plant sap. To control them, the best approach is to increase humidity and, if growing under glass, introduce a biological control . Alternatively, organic sprays can also be effective.

7

Codling moth

These moths are responsible for the maggots found in apples. To avoid these, spray emerging caterpillars twice with bifenthrin , starting in midsummer. Another useful method involves hanging pheromone traps in late spring to catch male moths and prevent them from mating.

8

Winter moth

Winter moth caterpillars hide inside webbed leaves on fruit trees during the spring. One effective way to control these pests is by applying sticky traps to capture the adult moths before they lay eggs.

9

Scale insects

Image: efraimstochter

Scale insects cluster on branches and beneath leaves, often leading to poor plant growth. Other common symptoms include sticky excretions (called honeydew) and the development of sooty mold, especially on evergreens. The solution is to wash off the mold and spray the plant with horticultural oil .

10

Viburnum beetle

Image: Grant Ofstedahl

The Viburnum beetle and its larvae can create holes in the leaves. The answer to this is to spray the areas affected during the spring with bifenthrin or thiacloprid .

11

Adult vine weevil

Image: Henry Lai

The adult weevil is a nocturnal, flightless insect that makes notches in the leaves of your plants. To control this pest, apply nematodes by mixing them with water and applying the solution to the soil in the affected area.

12

Rose slug

Image: Naoki Suzuki

The rose slug is easy to overlook until its feeding starts to damage the leaves. Rose slugs feed on the undersides of leaves, out of sight, nibbling on the tissue between the veins. By the time they’re done, the leaves often resemble skeletons.

Luckily, the solution only requires blasting the slugs off the roses with a spray of water or treating them with spinosad, a bioinsecticide derived from soil bacteria.

Corn Flakes

Image: Sten Ritterfeld

Who hasn't started their day with a bowl of Corn Flakes at least once? While Corn Flakes weren't exactly the first packaged cold cereal product sold in America, they are undoubtedly the most iconic. As early as 1902, William Keith Kellogg began mass production of his first cereal after proving its efficacy and popularity with patients at the Battle Creek Sanitarium, where he worked alongside his prestigious doctor brother.

The Kellogg brothers were focused on offering a healthier alternative to the traditional pork-and-beef heavy English-style breakfasts that most Americans were eating at the end of the 19th century. Therefore, they developed a process that allowed them to transform thin slices of cereal into small toasted flakes of wheat or corn. Since then, Corn Flakes, combined with fresh milk, have been one of the most popular breakfasts among Americans, young and old.

Cheerios

Did you know that a one-ounce serving of Cheerios contains nearly 250 individual "O's."? Crazy, right? Introduced in 1941 by the American company General Mills, Cheerios is one of the first oat-based ready-to-eat cereals and remains one of the most widely consumed in the United States.

Back in the 1930s, General Mills engineers tested more than 500 formulas and experimented with 10 different shapes and sizes before perfecting the now-iconic "O." They finally came up with the delicious cereal that offers the nutrients of 4 cereals: oats, corn, wheat, and rice. Today, there are about 20 different flavors of Cheerios available in the U.S., including Honey Nut, Chocolate, and Apple Cinnamon. Which one is your favorite?

Rice Krispies

Kellogg’s is one of the most influential breakfast cereal companies in the United States and the world, and we have them to thank not only for Corn Flakes but also for our beloved Rice Krispies. This breakfast cereal made from crispy rice first appeared on the shelves in 1928. It was revolutionary at the time because the company used a new patented process called "oven-popping" to manufacture them.

Rice Krispies’ success may have been due to its claim that the cereal would remain floating even after 2 hours in milk. The brand's classic slogan honoring this unique quality—"Snap! Crackle! Pop!"—was introduced around 1939 and is still used on packaging today. For decades, Rice Krispies has been one of the most popular cereals among consumers, so much so that even the Rolling Stones recorded a short song for a television commercial promoting the brand in 1964. Do you remember the catchy tune?

Cap'n Crunch

Image: Samantha Gades

Cap'n Crunch cereal, a combination of corn and oats, was developed in the early 1960s by Pamela Low, a flavorist who was inspired by a brown sugar and buttered rice recipe from her grandmother. Since its debut, additional flavors have been introduced, including Berries, Peanut Butter, and Chocolate.

But did you know that Cap'n Crunch’s full name is Horatio Magellan Crunch ? The iconic cartoon mascot was developed for the Quaker Oats Company by Allan Burns, a screenwriter and television producer who later co-created popular shows like The Munsters and The Mary Tyler Moore Show . Since its introduction in 1963, the late 18th-century naval captain, born on Crunch Island—a magical land in the Sea of Milk—has won the hearts (and bowls) of countless consumers across America.

5

Trix

Image: Sascha Bosshard

General Mills introduced Trix in 1954 as the first fruit-flavored cereal. Initially, it wasn’t marketed exclusively for kids, but because of the bright colors, it soon became a favorite among the little ones. When Trix was first launched, it featured round cereal balls in three flavors: "Raspberry Red," "Orange Orange," and "Lemony Yellow." It wasn't until 1991 that Trix became the first fruit-shaped breakfast cereal.

But as with other brands on this list, Trix is best remembered for its mascot rather than the cereal itself. In fact, the Trix Rabbit is one of the single longest-running ad campaigns in television history. Since the 1960s, the brand has kept the same character, the same slogan—"Trix are for kids!"—and the same storyline: the rabbit’s endlessly thwarted attempts to steal a box of cereal.

6

Frosted Flakes

Image: Engin Akyurt

If we talk about the sweetest cereals on the market, we cannot fail to mention Frosted Flakes. The concept and technology of a "frosted" cereal was developed in 1939 by Jim Rex, a salesman from Philadelphia who unfortunately didn’t have much success with his product Ranger Joe Wheat Honnies. The idea, though, was soon adopted by the breakfast cereal industry, and by 1952, Kellogg introduced Sugar Frosted Flakes to its lineup.

That same year, Kellogg launched a campaign featuring Tony the Tiger, Frosted Flakes’ famous mascot, who proudly declared, "Sugar Frosted Flakes are Grrr-reat! The slogan and the character became so popular in the United States that it's probably more quintessential than the cereal itself.

7

Lucky Charms

Image: Céline Druguet

The mini marshmallows found in Lucky Charms, whose technical and copyrighted name is Marbits , were invented, along with the cereal, by General Mills product developer John Holahan in 1963. One morning, he cut up a few orange marshmallow Circus Peanuts, mixed them into a bowl of Cheerios, and was delighted with the result. The rest, as they say, is history.

Lucky Charms is inspired by Irish culture. Its mascot, Lucky the Leprechaun debuted on St. Patrick's Day in 1964. The successful combination of this endearing character, delicious shaped oat pieces, and colorful little marshmallows was quickly embraced by children around the world. Tasty, crunchy, and fun, this cereal has undeniably revolutionized American breakfasts forever.

8

Froot Loops

Image: Yusuf Timur Çelik

Toucan Sam has been a part of our lives for more than 60 years now. Kellogg’s iconic mascot—a blue, anthropomorphic toucan with the ability to smell Froot Loops from great distances—was introduced alongside the O-shaped cereal in 1963.

Froot Loops were developed after Kellogg attempted to displace General Mills' Cheerios from the market. The idea of introducing fruity flavors proved to be a success, even though, years later, the company admitted that the different colors did not correspond to unique fruit flavors. In recent years, Froot Loops have faced criticism for their use of artificial colorings and high sugar content. Yet, they still have plenty of fans and they remain one of the best-selling cereal brands in America.

9

Cinnamon Toast Crunch

Image: Francisco Jacquier

Another popular breakfast cereal created by General Mills is Cinnamon Toast Crunch. In fact, the company sells over 100 million boxes a year of this brand alone, putting it just behind Cheerios and Frosted Flakes in sales. How about you—do you have a box of Cinnamon Toast Crunch waiting in your pantry?

These delicious little squares of whole wheat and rice, topped with cinnamon and sugar, were first launched in 1984 and were an instant hit. And it makes sense, given that, in a way, they were invented by a child. Cinnamon Toast Crunch was developed by General Mills scientists and product managers after an unnamed child suggested the idea of a cinnamon toast-flavored cereal during a radio contest. Since then, it has remained one of America's favorite cereals and we don't expect its popularity to wane any time soon.

10

Life

Image: Binyamin Mellish

More than 60 years after its creation, Life remains one of the top 10 best-selling cereal brands in the United States. Introduced on the market in 1961 by the Quaker Oats Company under the slogan "The most useful protein ever in a ready-to-eat cereal," Life is a multigrain cereal enjoyed by millions of family households across the country.

Like its competitor Trix, Life has also made history in marketing and advertising. A famous Life commercial featuring Little Mikey, a hard-to-please four-year-old boy, aired nationally from 1972 to 1984, making it the longest-running commercial in television history . Have you seen it? We bet you have!
