Background: Wagner was born to German immigrants Peter and Katheryn Wagner in the borough of Chartiers, in what is now Carnegie, Pennsylvania. Wagner was one of nine children. As a child, he was called Hans by his mother, which later evolved into Honus. "Hans" was also an alternate nickname during his major league career.
Context: Wagner was not finished playing baseball after his retirement from major league baseball. He managed and played for a semi-pro team. After retirement, Wagner served the Pirates as a coach for 39 years, most notably as a hitting instructor from 1933 to 1952. Arky Vaughan, Ralph Kiner, Pie Traynor (player-manager from 1934-1939), and Hank Greenberg (although, Greenberg was in his final major league season in 1947, his only season with the Pirates, and very well established) all future Hall of Famers, were notable "pupils" of Wagner. During this time, he wore uniform number 14, but later changed it to his more famous 33, which was later the number retired for him. (His entire playing career was in the days before uniform numbers were worn.) His appearances at National League stadiums during his coaching years were always well received and Wagner remained a beloved ambassador of baseball. Wagner also coached baseball and basketball at what is now Carnegie Mellon University.  In 1928, Wagner ran for sheriff of Allegheny County, Pennsylvania but lost. He was made deputy county sheriff in 1942. He also ran a well-known sporting goods company. A sporting goods store bearing the name "Honus Wagner" operated in downtown Pittsburgh for 93 years before closing permanently in 2011.  The Pirates hosted the 1944 Major League Baseball All-Star Game at Forbes Field. Wagner was invited to be an honorary coach for the National League squad, the first time this honor was bestowed in Major League Baseball's All-Star Game.  Wagner lived the remainder of his life in Pittsburgh, where he was well known as a friendly figure around town. He died on December 6, 1955 at the age of 81, and he is buried at Jefferson Memorial Cemetery in the South Hills area of Pittsburgh.
