Earle Haas
Earle Cleveland Haas (born March 6, 1885 in McPherson County , Kansas , United States , † November 1981 ) was an American osteopath . He is best known as the inventor of the modern women's tampon (1929). He received his doctorate from Kansas City College of Osteopathy in 1918 and spent ten years in Colorado as a country doctor, after which he went to Denver in 1928 .
Inventions
He invented the elastic ring for the contraceptive diaphragm , the patent for which he was awarded $ 50,000, sold real estate, and was the president of a company that manufactured antiseptics .
Haas said he wanted to invent something better than “cloth flaps” that his wife and other women had to wear. The idea for tampons came to him by a friend in California that a sponge in the vagina used to menstrual bleeding to absorb. He developed a cotton stopper that had to be inserted using two cardboard tubes; he wanted the woman not to have to touch the cotton.
He failed to interest anyone in his invention (including the Johnson & Johnson company ). He finally sold the patent and trademark to Gertrude Tendrich, a Denver businesswoman, for $ 32,000 on October 16, 1933 . She founded the company " Tampax " and was its first president. Tendrich made her first Tampax tampons at home, using a sewing machine and Haas' tamping machine . Haas design tampons were first sold in the United States in 1936.
In 1969, the London Sunday Times named Haas one of the "1000 developers of the 20th century".
After the rights to the tampon were sold, Haas returned to his doctor's office and continued doing various business. He later regretted the rights sale, but was pleased that his invention was a success. He died in 1981 at the age of 96. He continued to try to improve the tampon until the end of his life.
