Jonathan Curedale Calvert ’53

Jonathan was an investment adviser and adventurer who died Aug. 23, 2018, in San Antonio, Texas. He was born in Cambridge, Mass., and came to Princeton from Exeter Academy. He joined Cottage Club, majored in history, and wrote his thesis on “Mosby’s Partisan Rangers.”

After graduation, Jonathan was commissioned as a second lieutenant in the Marine Corps and was deployed overseas to Japan and then to Korea. He remained in the Reserves until August 1968, when he retired at the rank of captain.

After his military service Jonathan worked in New York and Chicago before moving to Texas to found a securities brokerage firm with his college roommate, Richard “Dick” King. A regional firm bought their firm, and Jonathan became manager of its San Antonio branch. Later he partnered with Ed Glass and Edward Austin Jr. to create Glass, Austin & Calvert, one of the first registered investment-adviser firms in the region.

Jonathan was also a self-described adventurer who spent 50 years exploring remote corners of the world and climbed the highest peaks on six of the seven continents. In 2000 he was a member of an expedition that made the first successful crossing of South Georgia Island, following the 1916 route of the famous Antarctic explorer Sir Ernest Shackleton.

Jonathan is survived by his wife, Elizabeth; daughters Blair ’82, Sarah, and Mollie; stepson Edward; and eight grandchildren.
