Capt. John Notman Thorp, Jr., U.S.A.S.
I cannot provide any operational or technical answers to your inquiry, but
I can fill-in some of the biographical details.
John Notman Thorp, Jr., was born 17 July 1890, at Paterson, New Jersey,
the son of John Notman Thorp, an office clerk, & Margaret A. Thorp;
both parents were born in New Jersey, and their parents were all natives
of England. In 1914, he traveled to Hamilton, Bermuda, and returned
from there on 2 March 1914. He did not continue in the military after
the war: in 1920, he and his wife, Elizabeth, were living at his father's
house in Paterson; Thorp worked a route as a salesman. By 1930, they
were living in Chicago and he was employed as a "sales engineer" (that's
what the 1930 U.S. Census states) for an air compressor manufacturing
company. At the time he completed his W.W.II Draft Registration, in
1942, Thorp was living in New York City, and he was still traveling as
late as 20 June 1951, when he arrived in New York from an ocean
voyage. Thorp died in January, 1967, at Dunedin, Pinellas County,
Florida, six months short of his 77th birthday. I hope this was helpful.
