Marsden was born in the village of Thornhill, near Dewsbury, in Yorkshire, the youngest of eight children.
When he left school he was apprenticed to a wholesale druggist in Sheffield.
In 1816, he moved to London where he took up an apprenticeship to a surgeon-apothecary before setting up on his own. At the end of 1824 he enrolled as a student of surgery at Street Bartholomew"s Hospital under the famous surgeon and lecturer John Abernethy (1764–1831). In April 1827 Marsden passed his Membership of the Royal College of Surgeons examination to qualify as a full surgeon.
He became an Doctor of Medicine in 1838.
After discovering the difficulties the poor had in obtaining medical treatment, Marsden sought to establish a free hospital in London for which "poverty and sickness are the only passports". In 1828 he set up a small dispensary at 16 Greville Street, Hatton Garden, Holborn, which was named the London General Institution for the Gratuitous Cure of Malignant Diseases.
This was later constituted as the Royal Free Hospital, and moved to the Gray"s Inn Road in the 1840s. A few years later, Marsden turned his attention to cancer sufferers and, in 1851, set up another small establishment in Cannon Row, Westminster.
This grew into the Brompton Cancer Hospital (now the Royal Marsden Hospital, Fulham Road site).
Marsden married Ann Bishop, known as Betsy-Ann, in 1820. William Marsden died in 1867. He is buried in West Norwood Cemetery, South London.
