My love of Godzilla started as a young child and Haruo's Godzilla was the one that drew me in. His passing on August 7th, 2017 was a great loss. Even though he only portrayed Godzilla for first 12 movies, to me he will always be "Mr. Godzilla".
(* from Wikipedia about Haruo)
Haruo Nakajima (中島 春雄 Nakajima Haruo) (January 1, 1929 – August 7, 2017) was a Japanese actor, best known for portraying Godzilla in twelve consecutive films, starting from the original Godzilla (1954) until Godzilla vs. Gigan (1972). He also played various other giant monsters in kaiju films, including Mothra and The War of the Gargantuas, and also appeared in a minor role in the Akira Kurosawa film Seven Samurai.
