Image of Eckert's death notice in the New York Times, 25 August 1971 (see text version HERE). Source: Eckert's Find A Grave site, compiled by his grandniece Ruthie Eckert Cacchione in 2017, who notes that the obituary incorrectly states his wife's name as Penelope Applegate. His wife's name was the former Dorothy Applegate. They had three children: Penelope, John and Alice.
