The Age Melbourne, Victoria, Australia Saturday, June 19, 1897 — The reported death of Steinitz, since contradicted, led the “Rochester Post Express” to revive the following anecdotes of the great master's little peculiarities:— … The happiness of “the Bohemian Caesar,” as Steinitz fondly called himself, was not unalloyed. Paul Morphy was his bête noire. He attempted to undermine the pedestal upon which Morphy's glory is everlastingly established. But he did not succeed. If Blackburne makes a brilliant combination, he calls it a “bit of Morphy.” But no one ever heard anybody call a brilliant finish a bit of Steinitz…”
“Morphy would beat anybody alive today.”
— Bobby Fischer
