Thomas Ignatius Maria Forster was an English astronomer, physician, naturalist and philosopher. An early animal rights activist, he promoted vegetarianism and founded the Animals' Friend Society with Lewis Gompertz. He published pamphlets on a wide variety of subjects, among other things, morality, Pythagorean philosophy, bird migration, Sati, and "phrenology", a term that he coined in 1815.
Life
Forster was born in London, the eldest son of Thomas Furly Forster of Walthamstow who was a botanist, and follower of Jean-Jacques Rousseau. He did not have the conventional classical literary education, but learned some science from his uncle Benjamin Meggot Forster. The Great Comet of 1811 aroused his interest in astronomy, a science which he continued to pursue, and eight years later, on 3 July 1819, he himself discovered a new comet. He declined a fellowship to the Royal Society in 1816 as he disliked some of the rules. He matriculated at Corpus Christi College, Cambridge, in order to study law, but soon abandoned it to study medicine, taking his degree in 1819. Two years before, he had married Julia, daughter of Colonel Mark Beaufoy, and taken up residence at Spa Lodge, Tunbridge Wells. After the birth of his only daughter he moved to Hartwell in Sussex, and then spent three years abroad. It was during this period that he converted to Catholicism. After his return to England he became a fellow of the Royal Astronomical Society and helped to found a meteorological society along with Sir Richard Phillips, which had only a brief existence. After his father's death in 1825, he took up his residence in Chelmsford in order to be near his daughter, then a pupil at Newhall Convent. Here he undertook a series of researches on the influence of atmospheric conditions on diseases, and particularly on cholera which also involved a balloon ascent in April 1831. In 1833 he again went abroad, where he spent most of his remaining years, settling finally in Bruges. He continued writing during the latter part of his life, including poetry. He also composed selections for the violin. He numbered among his friends authors and scholars of his time, such as Thomas Gray, Richard Porson, Percy Bysshe Shelley, Thomas Love Peacock, William Herschel, and William Whewell. He became a vegetarian, following a Pythagorean diet, and along with Lewis Gompertz, founded the Animals' Friend Society in 1833. He lived in Bruges from 1842 until 1852. He then moved to Brussels, where he died.
