Phar Lap - New Zealand racehorse and Aussie icon during 1920s and early 1930s. He measured staggering 17.1 hands high while his heart was 1.5 times larger than average horse heart. Phar Lap (Thai for "Lightning") had 37 wins in 51 races, and set 8 track records before his mysterious death in 1932. Many speculated that U.S. gangsters fearing big losses poisoned the horse. 70 yrs later forensics proved he ingested large dose of arsenic just before death, though a source wasn't found.
