His son contracted arthritis after having strep throat, and suffered from severe joint pain.

By 1968, the Jacuzzi we all know and love was born.

2. In 1972, Nike co-founder Bill Bowerman set out to design a revolutionary running shoe, and used his wife's waffle iron to create a sole that he believed would help runners increase their speed. Nike made 12 versions of the shoe for runners to use in the 1972 Olympic trials.

In 2019, the "waffle shoe" became the most expensive sneaker to ever be sold at auction. Canadian entrepreneur Miles Nadal bought the shoes for $475,000. They were actually part of an auction of the world's rarest 100 sneakers. Nadal ended up purchasing the 99 other shoes for a combined $850,000.

3. H.H. Holmes is considered America's first serial killer. Holmes is believed to have killed 27 people by luring them into his "Murder Castle," which had outfitted with secret passageways, trapdoors, and torture rooms. After killing his victims, Holmes would transport them to his basement using an elaborate elevator system, and then would dissect their bodies.

Holmes, who changed his name to reflect his love of Sherlock Holmes, grew up wealthy and enrolled in medical school around 1880. During his years at school, he was known for criminal activity, and was caught robbing graves to steal cadavers to sell. In the mid-1880s, he abandoned his wife and children and moved to Chicago, where he built his murder castle, just in time for the 1893 World's Columbian Exposition.

Holmes was so charming that he easily could coerce fairgoers to come into his castle, where he would kill them and examine their bodies. In 1894, he was arrested in Boston on suspicion of fraud. The evidence from his arrest linked Holmes to the murder of Benjamin Pitezel, who was one his business associates. Historians have had difficulty determining the exact extent of Holmes' crimes, but it is believed that he is responsible for at least 27 murders. Holmes was found guilty for Pitezel's murder, and was executed in 1896.

6. Some believe that singer Sam Cooke eerily predicted his own death in his song "Frankie and Johnny." The song was a reference to two women, both named Frankie, who killed their husbands in the 1800s. Cooke recorded his own version of the song, which had been around for decades at that point, in 1964. Some of the song's lyrics include, "Frankie reached down in her pocketbook / And up with a long .44 / She shot once, twice, three times / And Johnny fell on the hardwood floor."

A few months later, in December 1964, Cooke had taken a woman back his hotel room. A fight between the two occurred, and the woman took Cooke's clothes and ran out of the room. She would later testify that he had tried to rape her. Cooke, who had been drinking, asked the hotel manager if he could search her office for his clothes. She refused and shot Cooke three times, killing him.

8. If you're wondering where Ronald McDonald has been lately, blame the clown scare videos from 2016! After the videos, in which people dressed as clowns creepily stood in roads and parking lots to scare unsuspecting people, went viral, McDonald's began slowing phasing out Ronald. That wasn't the only reason why the restaurant started shifting their marketing away from the once-beloved mascot. Some criticized the fast-food chain for using a mascot to normalize unhealthy eating for young children.

9. In 1945, several crossword puzzles that contained answers that turned out to be the code names for D-Day military operations, appeared in the Telegraph, a British newspaper.

Dawe was arrested, but was found innocent.

12. Before World War II, basketball was a national pastime in Lithuania. After the country became a part of the Soviet Union, many talented Lithuanian players had to play for the Soviet teams. During the 1988 Olympic Games, the Soviet Union won gold, with four of the five starters being Lithuanian. By the 1992 Olympics, Lithuanian players who had found professional success in the NBA wanted to play for their home country, not the Soviet Union. The issue? They didn't have enough money to fund the trip.

After an article about the Olympic hopefuls was published in the San Francisco Chronicle, the Grateful Dead took notice. In fact, Sarunas Marciulionis, one of the Lithuanian players, played for the Golden State Warriors, which was the band's hometown team. The Dead were inspired by the team's story, and decided to fund the team. In addition to paying for the players to compete, they designed red, yellow, and green tie-dye shirts with the band's signature skeleton dunking a basketball for the players to wear during warm-ups. The team ended up defeating Russia to take home the bronze, and wore their warm-ups while accepting their medals. The shirts soon became the must-have souvenir of the games.

15. Before the 1959 release of Some Like It Hot, all movies had to cooperate with the Hays Code. Some of the code's rules included bans on nudity, profanity, and interracial or gay relationships. Studios had to cooperate with the code to avoid government censorship.

While movies like Gone With the Wind had previously tried to challenge the code, the filmmakers behind Some Like It Hot completely undermined the rules. The film featured LGBTQ+ themes, and showed men wearing dresses and makeup. As a result, the movie did not get the seal of approval for following the code, yet went on to be a box office hit. By 1968, the Hays Code was completely abandoned.

The movie, about a group of teens (including Patrick Swayze) fighting against Soviet Union soldiers who invaded their hometown, was released on August 10, and wasn't actually the first to be given the rating. That designation goes to The Flamingo Kid, but Red Dawn beat the movie to theaters.

The M rating was later changed to PG.

When band member Dennis Wilson drowned in 1983, the band wanted to honor him by burying him at sea. All sea burials must be approved by admirals or military officials. Reagan approved the burial, and is believed to be the first time a president had become involved in a civilian funeral matter. Wilson was buried at sea in January 1984.

22. And finally, Frances Perkins became the first female Secretary of Labor after witnessing the horrors of the Triangle Shirtwaist Factory fire. Perkins was having tea with friends in New York City when she heard sirens. She followed them to the Triangle Shirtwaist Factory, where she witnessed dozens of women jumping out of the building to escape the fire. Soon after, Perkins became dedicated to labor causes, and was hired as the executive secretary of a citizen's safety committee on the recommendation of President Theodore Roosevelt.

Perkins' work on the committee helped create laws that made workplaces safer than ever. By 1928, she served as New York's Industrial Commissioner while Franklin Delano Roosevelt was governor. When Roosevelt was elected president in 1932, he tapped Perkins to become the first female Secretary of Labor. She went on to help develop key elements of Roosevelt's New Deal, and was the nation's longest-serving labor secretary. Perkins was a driving force in getting people back to work after the Great Depression, and even fought for universal healthcare while in office.
