Born in East Lancashire, Marsden lived in Rishton and attended Queen Elizabeth's Grammar School, Blackburn, where an inter-house trophy rewarding academic excellence ('The Marsden Merit Trophy') bears his name.
He met Ernest Rutherford at the University of Manchester. While still an undergraduate he conducted the famous Geiger–Marsden experiment, called the gold foil experiment, together with Hans Geiger in 1909 under Rutherford's supervision. In that same year he helped Geiger to develop the Geiger counter. In 1915 he moved to Victoria University College in New Zealand as Professor of Physics; Rutherford recommended his appointment there.
Marsden served in France during World War I as a Royal Engineer in a special sound-ranging section and earned the Military Cross. Following the war he became New Zealand's leading scientist, founding the Department of Scientific and Industrial Research (DSIR) in 1926 and organizing its research particularly in the area of agriculture. During World War II he worked on radar research and in 1947 became scientific liaison officer in London. He died at his home in Lowry Bay, Lower Hutt on the shores of Wellington harbour in 1970.
