John P. Spence's description of the origin of the term “
frogman
” comes from Patrick Kiger, “John Spence: Fighting Frogman,”
AARP blog, posted November 5, 2013,
http://blog.aarp.org/2013/11/05/john-spence-fighting-frogman/
. The author also interviewed Spence in 2003. (Over the course of twenty-two years, he has conducted more than four thousand interviews with World War II veterans, including interviews with five hundred operational members of the OSS. The interviews were cross-checked with the documents in the National Archives. He has spent more than a decade researching hundreds of thousands of records for the OSS and has written four books on the subject. Thousands of documents were used to write this book.)
