Cousteau did use the Denise sub on the Niagara when here. We had a Triton sub dive project set up for the past weeks to dive the Niagara but on hold due to the Covid-19 situation. Both divers were involved with the Thai cave rescue - Harry was the Doc who sedated the boys and Craig assisted with diving them out - they have recently co-written a great book on the rescue well worth a read.
