SONAR True basically in principle but this doesn't fit, and I think that the answer is ASDIC or Anti-submarine Detection Investigation Committee, the former US name.
The Royal Navy had Asdic for submarine detection. Initially it was quite primitive. I'm thinking Sonar, as such, is more recent than WW2.
Active sonar was a huge advance. U-boats could run almost silently if needed, so hydrophones were useless at times. ASDIC allowed warships to find out exactly where a sub was hiding, and therefore let them use depth charges. It wasn't perfect, but it presented u-boat captains with a challenge: how do you escape from something that can't be escaped? Anti-sonar coatings made detection harder but not enough to escape location after the convoy or fleet got suspicious.
Most likely it was some unknown bosun's mate that worked in the sonar lab at the Navy Bureau of Ordinance.
World War 2 ++++ Primarily, Sonar, developed from the ASDIC systems used for hunting enemy submarines; and in pursuance of that developed the study of the complex nature of the bodies of salt water that are the oceans.
