Jackie Robinson in 1946
On October 23, 1945, the Brooklyn Dodgers announced that they had signed Jackie Robinson, assigning him to their International League team, the Montreal Royals.
Branch Rickey, the Brooklyn Dodgers General Manager, believing he "knew" Florida, thought his team could train there, ruffling as few feathers as possible. Robinson and his wife were instructed by Rickey not to try to stay at any Sanford hotels. He and his wife didn’t eat out at any restaurants not deemed “Negro restaurants." He didn't even dress in the same locker room as his teammates.
As soon as the citizenry became aware of Robinson's presence, the mayor of Sanford was confronted by a "large group of white residents" who "demanded that Robinson...be run out of town."[10]
On March 5, 1946, the Royals were informed that they would not be permitted to take the field as an integrated group. Rickey was concerned for Robinson’s life and sent him to stay in Daytona Beach. His daughter, Sharon Robinson, remembered being told, "The Robinsons were run out of Sanford, Florida, with threats of violence."
In his 1993 book, A Hard Road to Glory: A History Of The African American Athlete: Baseball, tennis great Arthur Ashe wrote in response, Rickey "moved the entire Dodger pre-season camp from Sanford, Florida, to Daytona Beach due to the oppressive conditions of Sanford."
