author
Best known for writing clearly about big scientific and religious debates, this English schoolmaster-turned-freethinker brought late Victorian controversies to a wide general audience. His most noted book takes on a central question in early evolutionary theory: whether acquired traits can be inherited.

by W. P. (William Platt) Ball
William Platt Ball (1844–1917) was an English schoolmaster, author, and freethinker. Sources available online consistently connect him with secular and rationalist writing, and identify him as the author of Are the Effects of Use and Disuse Inherited?, first published in 1890.
That book examines a major 19th-century evolutionary debate associated with Herbert Spencer and Charles Darwin. It is remembered for presenting a complicated scientific argument in a way that general readers could follow, which helps explain why it has continued to be reprinted and preserved in digital libraries.
Some online sources also describe him as having left teaching to work with The Freethinker, a British secular journal. Because detailed biographical information is relatively scarce in the sources I could confirm here, Ball is best introduced through his work: a writer interested in evolution, rational inquiry, and clear public argument.
