Deletion of Karst Hoogsteen

Comment: When I first saw the article it looked like utter crankery, but Hoogsteen pairs really are notable (maybe 500 hits for that phrase in Google scholar), and (assuming it's the same Karst Hoogsteen) he has citation counts of 1234, 271, 264, 210, etc., a clear pass of #C1. But it seems very difficult to obtain any reliable information about him. He worked for Caltech in the 1950s? And later for Merck? Even that much is hazy
