A tireless popularizer of science, this American editor and inventor helped bring electricity and new technology within reach of everyday readers. He is also remembered for guiding early science fiction in the pages of Amazing Stories during the genre's formative years.

by T. O'Conor (Thomas O'Conor) Sloane
Born in New York City on November 24, 1851, Thomas O'Conor Sloane built an unusually wide-ranging career as a scientist, inventor, teacher, editor, and author. He earned a Ph.D. in electrical engineering and became known for explaining technical subjects in clear, practical language for general readers.
Sloane wrote numerous books on electricity and applied science, including The Standard Electrical Dictionary, a major reference work of its time. He also served as editor of Scientific American from 1886 to 1896, helping shape how late 19th-century readers learned about new inventions and scientific ideas.
Later in life, he became one of the key editorial figures in early science fiction. From 1929 into the 1930s, he edited Amazing Stories, the pioneering magazine that introduced many readers to the developing genre. He died in 1940, leaving behind a legacy that connects practical science writing with the early history of modern speculative fiction.
