Horatio Caro

Horatio Caro (5 July 1862 – 15 December 1920) was an English-German chess player, of world-class Master strength for about a decade, from the late 1880s to the late 1890s, a frequent winner of significant German events. He was a regular competitor for 30 years in Master events. Caro is principally known as the co-inventor of the Caro–Kann Defence, a heretofore virtually unknown opening variation, which he analyzed, published, and played from the mid 1880s.

Caro was born in Newcastle upon Tyne, England, but spent most of his chess career in Berlin, Germany, having moved there when he was two years old.
