Sir Nicholas Winton - The 'British Schindler' - has been honoured as the first inductee to the Rotary International's Peace Hall of Fame.
The 104-year-old saved more than 600 mainly Jewish children from a Nazi occupied area of Czechoslovakia in 1939.
However, his incredible deeds were only discovered more than 50 years later by his wife, Greta.
Renata Laxova and Gerard Friedenfeld, two of the children he saved, collected a plaque on his behalf at a ceremony at the Illinois Holocaust Museum and Education Center.
Sir Nicholas has been a member of Maidenhead Rotary Club since 1969.
A campaign to see Sir Nicholas nominated honoured with the Nobel Peace Prize has ended in disappointment.
He was nominated for the honour by students in the Czech Republic earlier this year but pipped to the prize by the Organization for the Prohibition of Chemical Weapons (OPCW) for its extensive efforts to eliminate chemical weapons.
