Entrepreneur. He was an English-born, former steel mill worker, who is credited as the inventor of the hot dog in a roll. Harry M. Stevens was called during his lifetime the "world's greatest sporting caterer," "the man who parlayed a bag of peanuts into a million dollars" and "a true pioneer in the field of gastronomy." After immigrating to New York City in 1882, he and his family eventually settled in Niles, Ohio. He attended a minor league baseball game and saw the need for a new-and-improved scorecard, but later had the better idea of a "barker" to sell food by yelling to the fans, "Peanuts, popcorn." Having much success at a world series baseball game, he got the concession contract for Madison Square Garden in 1894, where his first jobs included feeding fans for a six-day bicycle race and the Westminster Kennel Club show. This followed with his concessions at not only baseball games, but football games, wrestling, boxing, polo matches and horse racing, to name a few. At first, he served cheese sandwiches and beer, ice cream, a cold bottle of soda with a straw, various candies, and of course, peanuts and popcorn. On a cold spring day in 1901, the Polo Grounds crowd turned down his usual menu of delights until he had his workers place warm frankfurters or sausages, with mustard and relish, inside warm rolls. Originally, they were called "dachshund sandwiches," but a few years later, "New York Journal" sports cartoonist Tad Dorgan had trouble with the spelling, dubbing them instead as "hot dogs." Stevens introduced the hot dog on a bun to the world at the Louisiana Purchase Exposition in 1904. He had licensed vendors manning his concession stands. In 1926 he claimed he had the biggest catering service in the world with concession stands not only in New York City for various events, but Chicago, Maryland, West Virginia, Florida, Mexico and even Cuba and becoming a million-dollar business. At his death, he held contracts for concessions at the five major-league parks in New York and Boston. Harry Mozley Stevens's enterprise was known as Harry M. Stevens, Inc. , having been incorporated in 1925. Although his work kept him from his family and hometown, he was part of Niles' community effort and helped bring the railroad to the area. The son of a lawyer with huge library, he was mainly educated at home and acquired a good business mind. He married in England, bringing a young daughter and two sons to the United States and later two more sons were born. All five of his children followed with his business endeavors and as well as other descendants into the 21st century. In 2013 a British memorial Blue Plaque was placed on his family's home in Derby, England. He died of pneumonia. His funeral service at Campbell's Funeral Church in Manhattan was attended by more than 500 people including baseball great Babe Ruth, tenor Enrico Caruso, Wild West hero-turned-writer Bat Masterson and silent-film sex symbol Rudolph Valentino. A private funeral was later held in his hometown in Ohio. His family donated land for a city park in Niles which bears his name. In 1939 the first national Hot Dog Day was declared.
