Founded as the Free Cancer Hospital in 1851 by Dr William Marsden at 1, Cannon Row, Westminster. Marsden, deeply affected by the death of his wife Elizabeth Ann from cancer, resolved to classify tumours, research the causes and find new treatments. The hospital quickly outgrew its original premises as it became apparent that some patients required inpatient care. It moved locations several times during the 1850s until its benefactors decided to find a permanent solution. Funds were raised to build a dedicated new building. Now known as the The Royal Marsden.
