Defenseman Andy Branigan played his first NHL game at the age of 18 as a member of the New York Americans in the 1940-41 season. He dressed for six games that year, scoring his first goal. In 1941-42, Branigan played 20 games with the team, renamed the Brooklyn Americans, before leaving the team for the duration of World War Two. As it turns out, he never again played in the NHL.
Branigan returned to professional hockey for the 1945-46 season, and played the next 13 years in the AHL, starting with one season in Indianapolis with the Capitals. In 62 games, Branigan scored four goals and 21 points. He then embarked on an eight-year stay with the Hershey Bears before spending four years with the Providence Reds.
In 1958-59, Branigan joined the EHL's Washington Presidents at the age of 36. He came back for one more season in the EHL with the New York Rovers and retired in the spring of 1960. Branigan played in just 26 career NHL games, scoring a goal and three points, but he had a pro career which spanned 20 years.
