Famous hyper-modern pioneer, Gyula Breyer, played Oppenheimer in a simultaneous exhibition, date unknown. Since Breyer died in 1921, Oppie must've been about 15 years old, showing an early and lifelong interest in chess. Odd that Oppenheimer was such a poor player, despite his genious in physics. The game itself is interesting, Breyer sacs his QUEEN in what appears to be a purely speculative attack, but it works beautifully. (and in a simul at that)
