His victory over Akio Kaminaga (1936-1993) in the open weight division is remembered for how he conducted himself after the bout.
The moment he won, excited Dutch delegation members leapt up on the tatami mat, and Geesink sternly warned them off with a hand gesture. Geesink was not smiling, nor did he strike a victory pose. His demeanor and posture amply revealed his respect for his defeated opponent, and many Japanese knew then that he was a "genuine" judoka.
