Background: Arnold Jacob Auerbach was one of the four children of Marie and Hyman Auerbach. Hyman was a Russian-Jewish immigrant from Minsk, Russia, and Marie Auerbach, nee Thompson, was American-born. Auerbach Sr. had left Russia when he was 13, and the couple owned a delicatessen store and later went into the dry-cleaning business. Little Arnold spent his whole childhood in Williamsburg, Brooklyn, playing basketball.
Context: Auerbach died of a heart attack on October 28, 2006 at the age of 89. NBA commissioner David Stern said, "the void caused by his death will never be filled" and players Bill Russell, K.C. Jones, John Havlicek and Larry Bird, as well as contemporaries like Jerry West, Pat Riley, and Wayne Embry universally hailed Auerbach as one of the greatest personalities in NBA history. Bird stated "Red shared our passion for the game, our commitment to excellence, and our desire to do whatever it takes to win." Auerbach was survived by his two daughters, Nancy and Randy. Auerbach was interred in Falls Church, Virginia at King David Memorial Gardens within National Memorial Park on October 31, 2006. Attendees included basketball dignitaries Bill Russell, Kevin McHale, Danny Ainge, and David Stern.  During the 2006-07 NBA season, NBA TV and NBA.com aired reruns of Auerbach's four-minute instructional videos known as "Red on Roundball" previously aired during NBA on CBS halftime shows in the 1970s and 1980s, and as a testament to his importance in the Boston sports world, the Boston Red Sox honored Auerbach at their April 20, 2007 game against the New York Yankees by wearing green uniforms and by hanging replicated Celtics championship banners on the "Green Monster" at Fenway Park. Boston won 7-6.  Prior to Boston's season opener against the Wizards, his signature was officially placed on the parquet floor near center court, thereby naming the court as "Red Auerbach Parquet Floor." The ceremony was attended by his daughter Randy and some of the Celtics legends. The signature replaced the Red Auerbach memorial logo used during the 2007 season.
