Thompson was born at
Framlingham, Suffolk. His father wished him to enter business, but he was eventually (by 1848) able to enrol in the Medical School of
University College London. He obtained his medical degree in 1851 with the highest honours in
anatomy and surgery and set up a practice at 35
Wimpole Street in London, where he lived and worked until his death in 1904. In 1853 he was appointed assistant surgeon at
University College Hospital, becoming full surgeon in 1863, professor of clinical surgery in 1866, and consulting surgeon in 1874. In 1884 he became professor of surgery and pathology in the
Royal College of Surgeons. Specializing in surgery of the
genito-urinary tract, and in particular in that of the
bladder, he studied in Paris under
Jean Civiale, who in the first quarter of the 19th century had developed a procedure to crush a
stone within the human bladder and who had invented an instrument for this
minimally invasive surgery. After his return from Paris, Thompson soon acquired a reputation as a skilful surgeon in that class of disease. In 1863, when King
Leopold I of Belgium was suffering from
kidney stones, Thompson was called to
Brussels to consult in the case, and after some difficulties was allowed to perform the operation of
lithotripsy. It was successful, and in recognition of his skill Thompson was appointed surgeon-extraordinary to the King, an appointment which was continued by
Leopold II. Nearly ten years later Thompson carried out a similar operation on the former Emperor
Napoléon III; however, the Emperor died four days after, not from the surgical procedure, as was proved by the
post-mortem examination, but from
uremia. In 1874 Thompson helped in founding the
Cremation Society of Great Britain, of which he was the first president; he also did much toward the removal of the legal restrictions on
cremation. He denounced the prevailing methods of
death certification in Great Britain; and in 1892 a select committee was appointed to inquire into the matter; its report, published the following year, was generally in line with his thinking.
Woking Crematorium finally became the first of its kind in the UK. Thompson's last public duty for the society, in 1903, was to open
Birmingham Crematorium, the country's ninth. Thompson died in April 1904 aged 83; his body was cremated at
Golders Green Crematorium, the first in London, which he had opened in 1902. ==Personal life==
