Samuel Ryder (24 March 1858 – 2 January 1936) was an English businessman, entrepreneur, golf enthusiast, and golf promoter. He originated the idea of selling garden seeds in "penny packets" and built a very successful business on the concept.
At the age of 50 he became an enthusiastic golfer and then from 1923 to 1925 he, together with his brother James, started sponsoring a number of golf tournaments and matches mostly at his home club of Verulam near St. Albans. From late 1925 he started employing Abe Mitchell as his private coach. In early 1926 the idea for a match between British and American professional golfers was proposed. Ryder became involved and sponsored the event. It had been his intention that the match would be the first Ryder Cup but it was later decided that the match would not be an official contest. The first official event did not take place until 1927 for which Ryder donated a gold trophy.
Ryder was born at Walton-le-Dale near Preston, Lancashire. He was the fourth of the eight children of Samuel Ryder Sr. (1823/4–1904), a gardener, and Elizabeth (née Martin) (1822/3–1904), a dressmaker. He had three elder and two younger sisters, and two younger brothers. He trained as a teacher at Owens College in Manchester (now Manchester University), but did not graduate due to ill health. Ryder first worked at a shipping firm in Manchester, and then for his father, whose business has expanded to include a Nursery, florist, and seed merchant. Friction with his father led Ryder to move south to London to join a rival seed merchant. Ryder married Helen Mary (née Barnard), known as Nellie, on 20 November 1890.
