Roger Bresnahan began his major league baseball career in 1897 as an 18-year-old pitcher and ended it in 1915 as a catcher; he famously introduced shin guards for the position. He was so widely admired that the Baseball Hall of Fame awarded him a plaque only six years after it opened. He played every position, coached, and managed. He survived a near-fatal accident on the field and, as a first responder, helped save lives during the aftermath of a horrific railroad crash. He was later principal owner and president of the Toledo American Association franchise for eight years. This first-ever biography covers Bresnahan's entire life and playing career as it intersected with American history.
