The German physicist and philosopher of science Heinrich Rudolf Hertz was born in Hamburg. Early in his student days he showed an interest in engineering but soon took up the study of physics, to which he quickly made important contributions, mainly in the study of magnetism and electricity. He studied in Berlin under Hermann von Helmholtz and Gustav Kirchhoff and inherited their interest in the philosophy of science. In 1883 he began teaching in Kiel, where he worked on James Clerk Maxwell's electromagnetic theory. He became professor of physics at the technological institute at Karlsruhe in 1885, where he produced his most celebrated work on electromagnetic waves. In 1889 he was appointed professor of physics to succeed Clausius at Bonn. He was in failing health, however, and he died five years later.

Hertz's most important book for philosophy is his Principles of Mechanics, written during...
