Walter Aubrey Kidd
He followed in the family tradition and studied Medicine at Corpus Christi College in Cambridge from 1870 later gaining his doctorate (MD) at the University of London. He worked at Guy's Hospital in London and as a GP in Blackheath.
Kidd was a supporter of Lamarckian evolution. He took interest in studying the evolution of mammalian hair and wrote several books on this topic. He was the author of Use-Inheritance Illustrated by the Direction of Hair on the Bodies of Animals, 1901. The book argued for the inheritance of acquired characters, based on observations of the direction of hair on the bodies of animals. Herpetologist Inez Whipple Wilder wrote a seven page review of Kidd's The Direction of Hair in Animals and Man in the Science journal.
He also authored Initiative in Evolution.
He married Alice Harriet Benn (died 1947) in 1881.
They had four children: Alice Sophie Kidd, Walter Shirley Kidd, Edward Aubrey Kidd, and Hubert John Kidd.
