Ricou Browning passed on 2.27.23, which I missed somehow. Here is a short obituary From Entertainment Weekly:
"The actor who donned the Gill-man suit in extensive underwater sequences in
Creature From the Black Lagoon, died Feb. 27 at 93. Browning, who reportedly could hold his breath for up to four minutes, was widely considered the last surviving actor to have played one of the original Universal monsters. He reprised the role in two sequels to the original 1954 film. Browning also worked extensively in marine coordination for television and film, often directing underwater sequences, including scenes in
Thunderball, Never Say Never, and
Caddyshack. He was also the creative force behind
Flipper, both the movie and the TV series, directing 37 episodes of the television show and co-writing the film."
Ricou was a prolific autograph signer for decades, and reputed to be a very nice man in person. He made hundreds of appearances at conventions over the years, and charged a small fee through the mail, which really could have been a lot more, considering his stature in the monster movie community, and also considering the fact that he was the last of the principal cast members of any of those movies who was still living.
Here is the most famous scene from the movie, it has come to be known as the "underwater ballet":
