Robert Fremont "Fish" Jones (?–1930) was a Minneapolis, Minnesota businessman and showman. His prominence led to him driving Ulysses S. Grant and William T. Sherman down Nicollet Avenue (later Nicollet Mall) in downtown Minneapolis for their post-war tours.
Jones came to Minneapolis from upstate New York in 1876. He got a job as a meat deliverer, but was unimpressed with the profession, so he quit it and invested $500 in a fish market on Hennepin Avenue. The fish market prospered so much that Jones was able to buy a front-page advertisement in the St. Paul Pioneer Press. It displayed him as a bird with oysters for wings. The advertisement earned him the nickname "The Oyster King" which stuck for the rest of his life. Owning the fish market also earned him the nickname "Fish".
Jones had a bear imported and tethered in front of his market to both amuse and scare customers. He also owned a camel and tigers which he kept on the third floor of his building in downtown Minneapolis. His fondness for animals was such that in 1886 he sold his fish market and moved west down Hennepin Avenue. On a three-acre farm, he built a zoo in which he put six lions from South Africa, cougars and other animals.
In 1906, Jones sold his zoo to the Roman Catholic Church who built the Basilica of St. Mary on its site after receiving complaints about noise from neighbors. He moved his zoo a quieter portion of town, the area around Minnehaha Falls. He rebuilt his zoo as the Longfellow Zoological Gardens, and a ⅔ scale replica of Henry Wadsworth Longfellow's house where he lived. He built his zoo up and by the late 1920s, it included a polar bear, seals and elephants.
