Robert Joseph Cousy (born August 9, 1928) is an American retired professional basketball player. Cousy played point guard with the Boston Celtics from 1950 to 1963 and briefly with the Cincinnati Royals in the 1969-70 season. Making his high school varsity squad as a junior, he went on to earn a scholarship to the College of the Holy Cross, where he led the Crusaders to berths in the 1948 NCAA Tournament and 1950 NCAA Tournament and was named an NCAA All-American for 3 seasons. Cousy was initially drafted by the Tri-Cities Blackhawks as the third overall pick in the first round of the 1950 NBA draft, but after he refused to report, he was picked up by Boston.

Cousy took up basketball at the age of 13 as a student at St. Pascal's elementary school, and was "immediately hooked". The following year, he entered Andrew Jackson High School in St Albans. His basketball success was not immediate, and in fact he was cut from the school team in his first year. Later that year, he joined the St. Albans Lindens of the Press League, a basketball league sponsored by the Long Island Press, where he began to develop his basketball skills and gained much-needed experience. The next year, however, he was again cut during the tryouts for the school basketball team.  That same year, he fell out of a tree and broke his right hand. The injury forced him to play left-handed until his hand healed, making him effectively ambidextrous. In retrospect, he described this accident as "a fortunate event" and cited it as a factor in making him more versatile on the court. During a Press League game, the high school basketball coach saw him play. He was impressed by the budding star's two-handed ability and invited Cousy to come to practice the following day to try out for the junior varsity team. He did well enough to become a permanent member of the JV squad. He continued to practice day and night, and by his junior year was sure he was going to be promoted to the varsity; but failing his citizenship course made him ineligible for the first semester. He joined the varsity squad midway through the season, however, scoring 28 points in his first game. He had no intention of attending college, but after he started to make a name for himself on the basketball court he started to focus on improving in both academics and basketball skills to make it easier for him to get into college.  He again excelled in basketball his senior year, leading his team to the Queens divisional championship and amassing more points than any other New York City high school basketball player. He was even named captain of the Journal-American All-Scholastic team. He then began to plan for college. His family had wanted him to attend a Catholic school, and he wanted to go somewhere outside New York City. Boston College recruited him, and he considered accepting the BC offer, but it had no dormitories, and he was not interested in being a commuter student. Soon afterward, he received an offer from the College of the Holy Cross in Worcester, Massachusetts about forty miles (64 kilometers) west of Boston. He was impressed by the school, and accepted the basketball scholarship it offered him. He spent the summer before matriculating working at Tamarack Lodge in the Catskill Mountains and playing in a local basketball league along with a number of established college players.
