J. W. Clawson was probably the first to publish a description of an object in triangle geometry now known as the Clawson point. Born in St. John's, New Brunswisk, Canada, Clawson received the A.B. degree in 1901 from the University of New Brunswick. In 1905, he received the A.M. degree from Cambridge University. From 1907 until his retirement in 1952, Clawson was Professor of Mathematics and Physics at Ursinus College in Collegeville, Pennsylvania. During the last six of these years, he was Dean of the College.
Clawson published a book of 63 pages - Geometry of Three Dimensions (Edwards Brothers, Ann Arbor, Michigan, 1938) - and several journal articles.
The Clawson point originates in one of Clawson's problem proposals in the American Mathematical Monthly: no. 3132, submitted in 1925, and solved in v. 33 (1926), page 285.
