Silvanus P. (Silvanus Phillips) Thompson

Born in York in 1851, Silvanus Phillips Thompson grew up in a Quaker family and went on to build a career that joined science, teaching, and writing. He became an important British electrical engineer and physicist at a time when electricity was rapidly changing everyday life.

Thompson taught and lectured widely, and he is closely associated with technical education through his work at Finsbury Technical College and later the City and Guilds of London Institute. Alongside his scientific work, he wrote books that aimed to explain complicated subjects in a direct, useful way.

Today he is best known to many readers for Calculus Made Easy, first published in the early twentieth century and admired for its friendly style. He died in 1916, leaving behind a reputation as both a serious scientist and an unusually clear guide for students.
