    Notes:

    John Wentworth Clawson (1881-1964) was born in St. John, New Brunswick. He took his bachelors and masters degrees from New Brunswick College in 1901 and 1905. In between he studied at Cambridge University in England. Clawson came to the department of mathematics and physics at Ursinus College in 1907. He taught at Ursinus and lived in Collegeville the rest of his life, spending the years 1947-1952 as dean of the college. Clawson was a charter member of the MAA in 1916 and was elected chairman of the Philadelphia Section in 1935. Earlier he served two one-year stints on the Program Committee (now the Executive Committee) of the section, in 1930 and 1933. Clawson retired as emeritus professor in 1952 at age 70. He was an inveterate problem solver, beginning with his published solution to a problem in the January 1909 issue of the Monthly, ending with the solution to an Advanced Problem in the June/July 1957 issue, and including solutions to over 50 other problems in between. J W. Clawson died in 1964 after having been an MAA member for 48 years.

    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:

    Annals of Mathematics:
    20 (1919) 232-261 The complete quadrilateral
    23 (1921) 40-44 More theorems on the complete quadrilateral

    American Mathematical Monthly:
    24 (1917) 71- An inversion of the complete quadrilateral
    26 (1919) 63- A theorem in the geometry of the triangle
    32 (1925) 169- Points on the circumcircle
    61 (1954) 161- A chain of circles associated with the 5-line
    63 (1956) 306- A chain of circles associated with the n-line
    65 (1958) 32- An n-line property

    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. (Source : Faculty Evansville.)
