Mary Beatrice Kenner Davidson invented the sanitary pad. Specifically, a sanitary belt with a moisture-proof napkin pocket, which made it much less likely that menstrual blood could leak. Unfortunately her invention was introduced to market thirty years after she invented it, because the company which first showed interest in the sanitary pad lost interest after realizing the inventor was African-American.
In 1957, Davidson was finally able to save up enough money to get her first patent independently. Pads had been sold since the 1920s. But Davidson’s version revolutionized the product by making it much, much more absorbent.
At a Tallahassee golf course, near the 7th hole, has been found a cemetery dating to the days of the American Civil War. With a naked eye can be seen barely-there depressions in the grass. But thanks to continued local remembrance of a graveyard for enslaved persons in the area, and a report based on historical records made to the country club, an archaeological team from the National Park Service brought ground-penetration radar (GPR) to the site in 2019 to investigate.
The GPR detected roughly 40 graves. They were the right shape, and the right depth, to be graves. The finding was then confirmed by human remains detection dogs.
Based on historical records, the graveyard has been connected with a plantation owned by the family of Edward Houston. The Houstons were a prominent slave-owning family in Savannah, Georgia. When Tallahassee was being settled by white colonists, two Houston family members purchased a half square mile in 1826. The records demonstrate that this would not have been a graveyard for white residents of the plantation, for the family. It would have been a final resting place for the enslaved persons who worked the plantation.
At this time, there are no plans to excavate in the cemetery, and disturb the dead. Efforts are focused on finding descendants of those who might be buried there.
New genetic research now suggests that when the ancient Inuits migrated from Siberia to North America they brought their dogs with them. Considered one of the toughest and strongest breeds, this ancient Siberian canine was so indispensable, the genetic research shows the Inuits used them exclusively. They did not even interbreed with the new dogs they found in North America. The new study showed that over 4,500 years, Inuit new dogs were and remained genetically distinct and physically different from the dogs who arrived earlier in North America.
Where the humans went they brought their dogs, so Inuit dogs rapidly dominated and spread eastward in the North American Arctic alongside their humans’ migration. Because the Inuit remained faithful to their sled dogs, the pre-existing native dogs were almost completely replaced.
This genetic distinction has been maintained through today, too. The study compared 922 Arctic dogs and wolves who lived over 4,500 years. Modern sled dogs, according to their genomes, are some of the last direct descendants of the breed the Inuit brought with them from Siberia.
In 3800 BCE, the Babylonian Empire took the world’s first known census – of farmgoods. They counted
and quantities of butter, honey, milk, wool, and vegetables.
In 2 CE,
China’s Han Dynasty took the oldest surviving census data, showing a
population of 57.7 million people living in 12.4 million households.
Chengdu, the largest city, had a population of 282,000.
The first modern census in Britain in 1801 didn’t ask people to list their ages.
The first census in the US in 1790 only cared about age if the person was a “free white male,” which was sorted by “16 years and upward” and “under 16 years.” All other categories were ageless.
Chile passed the first census law in South America.
Britain’s attempt to take a census in India in 1871 was difficult because there were rumors that
the goal of the count is to identify girls to be sent to England to fan
Queen Victoria during a heatwave.
In 1577, King Philip II of Spain wanted to know whom he was ruling and where in his vast kingdom they were. So his viceroy asked the indigenous groups in what is now Mexico to draw some maps for him.
In response, they drew maps blending indigenous and Spanish traditions. Sometimes rivers are straight, with tiny arrows in the middle, to indicate which way they flow. Paths have footprints or hoofprints in the middle, to indicate whether the paths can be walked or ridden. These beautiful maps, and their way of recording the landscape, are a silent testimony to the survival of indigenous worldviews into the late 1500s.
Most people think the pizzas they know and love – four cheese, pepperoni – were invented in Italy. But they were actually developed by Italian immigrants in the United
States, and then exported back to Italy. Syracuse University
anthropologist Agehananda Bharati calls this the “pizza effect.” Here are some other examples of when
elements of a nation’s culture developed elsewhere and were then reimported:
Mexico City’s Day of the Dead parade was invented for the James Bond film Spectre and then adopted by the city.
American blues music influenced English musicians in the 1960s, who then exported blues-rock to the United States.
Adapted from India’s chicken tikka, chicken tikka masala became one
of the most popular dishes in Britain before being re-exported to India.
Yoga became popular in India after its adoption in the West.
Salsa music originated largely among Cuban and Puerto Rican
immigrants to New York in the 1920s and then spread throughout the
Teppanyaki, the Japanese style of cooking on an iron griddle, grew to prominence in America in “Japanese steakhouses.”
On May 15th, 1976 this photograph was taken by Robin Hood. It shows Vietnam War veteran Eddie Robinson, sitting in his wheelchair with his son on his lap, watching the Chattanooga Armed Forces Day Parade. The Vietnam War had ended almost exactly 1 year earlier.
The photograph won the Pulitzer Prize for photography in 1977.
