Lyda

Lyda Moore Merrick (1890- 1987) was an American advocate for Blind people and the founder of The Merrick/Washington Magazine for the Blind, a national publication addressing the needs of Black people with visual impairments.

Eliza "Lyda" Conley (c. 1869 – 1946) was a Wyandot Native American and an American lawyer. She was the first woman admitted to the Kansas Bar Association. She was notable for her campaign to prevent the sale and development of the Huron Cemetery in Kansas City, now known as the Wyandot National Burying Ground. She challenged the government in court, and in 1909 she was the first Native American woman admitted to argue a case before the Supreme Court of the United States.

Lyda D. Newman (fl. 1892-1925) was an American hairdresser and inventor who was also an activist for women's suffrage. She held a patent for a novel hairbrush.

In the 1890s, Newman invented a hairbrush which contained evenly spaced rows of bristles with open slots to clear debris away from the hair and into a recessed compartment in the brush back. The brush also had a button which allowed the bristle holder to be removed from the back for cleaning of the brush.

The U.S. patent 614,335 was filed on July 11, 1898 and granted on November 14, 1898. The hairbrush she invented was described in her patent as "simple and durable in construction" and being "very effective when in use". Modern hairbrushes still use Newman’s design, with the only changes being aesthetic. Lyda’s invention changed the hair-care industry, due to the fact that her design made hairbrushes less expensive, easier to manufacture, and effective to use on textured hair.
