About John Ugelstad
John Ugelstad (31 March 1921 – 3 April 1997) was a Norwegian chemical engineer and inventor, known for discovering a process to manufacture monodisperse micropellets or microbeads and dynabeads. He was a professor at the Norwegian Institute of Technology and consultant for DuPont. == Early life and education == Ugelstad was born in Trondheim to Karen Stene (1898-1993) and Petter Endresen Ugelstad (1893-1975), a factory owner. He grew up and attended school in Trondheim. After graduating in 1941 he began to study chemistry at Norwegian Institute of Technology (NTH); the German occupation of Trondheim during World War II delayed his studies and he passed the engineering exam in 1948. == Career == After a few years in business, he worked a few years at Philips Group's research department in Eindhoven in the Netherlands and obtained a PhD at the University of Leiden in 1955. He was employed by SINTEF and since 1957 by the Institute of Industrial Chemistry at NTH. During a sabbatical in Norwegian's research department from 1964 to 1965, he was the brains behind a new and epochal theory of emulsion polymerization which replaced the former and well-established theories and was dominated the field. This work was in practice as important as the monodisperse spheres. In 1966 he became a professor at NTH where he stayed until 1991. Besides teaching and research, he took on a number of assignments for industry, including being the main consultant in theoretical polymer chemistry for DuPont.
