"My whole philosophy of Barbie was that, through the doll, the little girl could be anything she wanted to be. Barbie always represented the fact that a woman has choices."

363: Ruth Handler

Invented Barbie and Co-Founded Mattel Toy Company

Born: 4 November 1916, Denver, Colorado, United States of America

Died: 27 April 2002, Los Angeles, California, United States of America

Ruth served as president of Mattel for several of its most successful years. One of her more ingenious moves was to pay $500,000, otherwise calculated as the entire value of Mattel, to sponsor the Mickey Mouse Club. Her high stakes gamble paid off, and Barbara became the first toy manufacturer to successfully market directly to children instead of their parents.

As a survivor of breast cancer, she also founded Nearly Me which creates realistic looking breast prostheses.

When Handler died over a billion Barbies had been sold in 150 countries.

149) Florence R. Sabin

She was the First Female Professor at Johns Hopkins University, Beginning There in 1903

Born: 9 November 1871, Central City, Colorado, United States of America

Died: 3 October 1953, Denver, Colorado, United States of America

Florence was also the first woman elected to membership of the National Academy of Sciences in 1925.

In 1924, she became the first woman elected president of the American Association of Anatomists.

Florence was one of the first female physicians to focus on research instead of practicing medicine. She focused on embryology and histology. Florence even disproved the original theory of the origin of the lymphatic system by instead proving it begins from the veins in an embryo and grows out into the tissues from there.

She and her sister were raised by relatives after their mother died in childbirth and both received a good education for women of their time. Florence enrolled at Johns Hopkins in 1896 after saving for three years and was one of fourteen women in a class of forty-five.

She published her first research paper while she was still a medical student and became a faculty member in 1903 and an associate professor in 1905 yet when her boss died in 1917, she was passed over for the position by one of her former (male) students.

Her students protested for her, but she was named full professor of histology instead—which was still a first for a woman at the school.

In 1925, she moved to the Rockefeller Institute as the head of the cellular immunology department—the first woman to be a full member of the institute. Once she transitioned to Rockefeller, she finally started to receive the recognition she deserved.

Florence retired in 1938 and yet in 1944 joined the Colorado Post-war planning committee as a medical adviser.
