Silvanus P. (Silvanus Phillips) Thompson

Born in York in 1851, Silvanus Phillips Thompson was an English physicist, electrical engineer, and educator who became one of the best-known scientific writers of his day. He studied at the University of London, taught first at Bootham School, then at University College, Bristol, and later became professor of physics at the City and Guilds Technical College in Finsbury. In 1891 he was elected a Fellow of the Royal Society.

Thompson worked across electricity, magnetism, optics, and X-rays, and he was especially admired for explaining technical subjects in a way that ordinary students and working engineers could use. He wrote many books and lectures on electrical machinery and practical science, but he is most widely remembered for Calculus Made Easy (1910), a friendly introduction that remained popular long after his death.

He was also interested in the history of science and wrote studies of figures such as Michael Faraday and William Gilbert. That mix of hands-on science, teaching, and historical curiosity gives his writing a distinctive character: learned, energetic, and always eager to make knowledge useful.
