Also, currently the only living International Honorary Master for chess composition is Hannu Harkola (b. 1944) and the only living Honorary Grandmaster is Jonathan Penrose (1933-2021).
Yuri Averbakh (b. 1922) is both the earliest grandmaster (1952) and the oldest.
Other 1950s grandmasters include Aleksandar Matanovic (b. 1930), Borislav Ivkov (1933-2022), Oscar Panno (b. 1935), Boris Spassky (b. 1937) all in 1955 and Friðrik Ólafsson (b. 1935) in 1958.
Matanovic still looks great (video from his 90th birthday celebrations), couldn't find new pictures of Ivkov but apparently he still writes books and articles and Panno is still in good health, too. Couldn't find new pictures of Olafsson, but he released a book a while ago.
However Spassky, probably the most notable out of the people I've listed suffered strokes in 2006 and 2010, reported to be gravely ill in 2010 after his second stroke. Doesn't look great but I wouldn't be suprised if he'd still be alive in 10 years.
