At the Browns' reception Chris Von der Ahe said: "I am druly der boss manager of der boss club" and the crowd yelled: "Vats knocked is knocked and dats a home run."
-Sporting Life, October 21, 1885
I just wanted to document the fact that the Von der Ahe moniker of Der Boss President goes back at least to 1885. It's entirely possible and likely that it pre-dates this event. If I were of the mind to look into this, I would search October 1881 to October 1885.
The context of the remarks were a celebration in St. Louis of the Browns' 1885 AA championship.
