John Cowan (physician)
# John Cowan (physician)

John Cowan was an American physician and phrenologist who wrote on sexual health, women's rights, and the evils of tobacco.

His 1869 manual for married couples, The Science of a New Life, was endorsed by the suffragist Elizabeth Cady Stanton. It was issued in many editions, with parts of the original text expurgated to suit prevailing morality, such as his advice about contraception. It was re-issued with the new title of What All Married People Should Know in 1903. In his 1870 book, Self-help in the Attainment of Perfection of Character and Success in Life, he described himself as a "practical phrenologist".
