Sir Henry Solomon Wellcome (August 21, 1853 – July 25, 1936) was an American pharmaceutical entrepreneur. He founded the pharmaceutical company Burroughs Wellcome & Company with his colleague Silas Burroughs in 1880, which is one of the four large companies to eventually merge to form GlaxoSmithKline. He left a large amount of capital for charitable work in his will, which was used to form the Wellcome Trust, one of the world's largest medical charities. He was a keen collector of medical artefacts which are now displayed at the Wellcome Collection. Biography Wellcome was born in a frontier log cabin in what would later become Almond, Wisconsin, to Rev. S. C. Wellcome, an itinerant missionary who travelled and preached in a covered wagon, and Mary Curtis Wellcome. He had an early interest in medicine, particularly marketing. His first product, at the age of 16, was invisible ink (in fact just lemon juice), which he advertised in the Garden City (MN) Herald. He was brought up with a strict religious upbringing, particularly with respect to the temperance movement. His father was a strong member of the Second Adventist Church. He was a freemason. Pharmaceutical executive In 1880, Wellcome established a pharmaceutical company, Burroughs Wellcome & Company, with his colleague Silas Mainville Burroughs. They introduced the selling of medicine in tablet form to England under the 1884 trademark "Tabloid". Previously, medicines had been sold mostly as powders or liquids. Burroughs and Wellcome also introduced direct marketing to doctors, giving them free samples. In 1895, Burroughs died, aged 48, leaving the company in the hands of Wellcome. It flourished and Wellcome set up several related research laboratories. In 1924, Wellcome consolidated all his commercial and non-commercial activities in one holding company, The Wellcome Foundation Ltd. Personal life In 1901, Wellcome married Gwendoline Maud Syrie Barnardo, a daughter of orphanage founder Thomas John Barnardo. They had one child, Henry Mounteney Wellcome, born 1903, who was sent to foster parents at the age of about three. He was considered to be sickly at the time, and his parents were spending much time travelling. The marriage was not happy, and in 1909 the couple separated. After that Syrie (as she was known) had several affairs, including with the department store magnate Harry Gordon Selfridge, and the author William Somerset Maugham with whom she had a child (Mary Elizabeth) and later married. Wellcome sued for divorce in 1915,
