Thomas Andrews, Northern Irish chemist and physicist, died on this day in 1885 in Belfast. Andrews spent extensive time in school. He first attended the Belfast Academy and then the Royal Belfast Academical Institute, where he studied mathematics. In 1828, he went on to University of Glasgow to study chemistry, then Trinity College Dublin for classics with a distinction in science, and finally University of Edinburgh, where he was awarded a doctorate of medicine. He did his most important work as a professor of Chemistry at Queen’s University of Belfast, where he demonstrated the phase transitions between gases and liquids, and carried out a complete inquiry into the gas laws.
