Looks like the spelling is Kincsem …
Hesp was no proponent of keeping his horses in cotton wool. They ran often, and Kincsem was no exception. Her career started in 1876, when as a two-year-old, she ran ten times in ten cities in three countries–Germany, Austria, and Hungary–and won each contest. Her season started on June 21 in Berlin and ended October 29 in Prague. Inbetween were victories in Hanover, Hamburg, Doberan, Frankfort, and Baden-Baden in Germany, the Hungarian cities of Sopron and Budapest, and Vienna in Austria.
Kincsem raced seventeen times at three, before fans in Hungary, Austria, Germany, and what is now Czechoslovakia. As the season progressed and her unbeaten skein lengthened, she attracted larger and larger crowds to each racecourse appearance. Emperor Franz Josef of Austria, a partisan of steeplechasing, became a tremendous fan, never missing an opportunity to see Kincsem perform. And after each victory, the Emperor would send for Kincsem’s owner to personally congratulate him.
