The former-U.S. president got the nickname because of the leading role he once played in the motion picture “Knute Rockne, All American.” In that particular film, he portrayed George Gipp, a very good college football player who went by the nickname ‘the Gipper.’
"Dutch"...and while President, "The Great Communicator"Ronald ReAgan was know to many as The Great Communicator.
"Win one for the gipper" was said by Knute Rockne, American football coach.
George Gipp (aka The Gipper ) was the role that Reagan played in the movie Knute Rockne All-American.
He got the nickname from playing the role of George Gipp, Notre Dame football player , in a movie, Knute Rockne -All American.
In one of his movies (Knute Rockne- All American) he is remembered for saying when playing as George Gipp who was dying "win just one for the Gipper" and later in life used the quote "win one for the Gipper"
Ronald Reagan was a professional movie actor and played many parts, possibly the one you are asking about. He surely played the Gipper, legendary football player.
Ronald Reagan was known as the GIPPER. No one was known as the Gripper.
Actually, no president had this nickname. But you may be referring to a famous line in a 1940 movie, when then-actor Ronald Reagan spoke about winning one for the Gipper-- a college football player at Notre Dame named George Gipp, who died when he was only in his mid-20s. Unfortunately, the movie memorializes a story that may or may not have really happened. Yes, there was a George Gipp, but whether he actually asked his teammates in a death-bed scene to win the game for him is the subject of much debate. I refer you to an excellent article about this, from Sports Illustrated. https://www.si.com/vault/1991/12/30/125750/the-elusive-gipper-who-was-george-gipp-of-notre-dame-and-why-does-his-legend-live-on-when-so-many-others-have-faded
The character of George "The Gipper" Gipp appeared in the film Knute Rockne, All American .
"The Gipper" based on the fact that in the movie "Knute Rockne, All American" Reagan played the part of George Gipp whose nickname was "The Gipper". A line from the movie was "Win One for the Gipper" an appeal to the rest to win against all odds. "Win one for the Gipper" became a common slogan for Reagan and his suporters when he went into politics.
