Alan "Ollie" Gelfand (born 1963, New York) is the inventor of the ollie, a skateboarding trick.
Gelfand moved from New York to Hollywood, Florida with his family in 1972. Alan "Ollie" Gelfand started skateboarding in 1974 after his father bought him his first skateboard. In 1976 he won the South Florida Skateboard Championships. That same year the first concrete skateboard parks began to appear in the United States with the first being Skateboard City just up the coast in Port Orange, Florida. In 1977 Hollywood would get its own park called Skateboard USA and it would be here that Gelfand would get his first notice in the skate press. His first published photograph was taken by Craig Snyder, a fellow Hollywood skater and photographer. It would be another Hollywood skater by the name of Scott Goodman who would give Gelfand his nickname of "Ollie" and who would name Gelfand's accidental aerial lipslide an Ollie Pop.
Skateboard USA with its imperfect walls was atypical of the first-generation skate parks and it was the over-vertical sections of the park which played a significant role in Gelfand's development of the Ollie Pop. In late 1977 California pro Stacy Peralta visited the Solid Surf Skate Park in Fort Lauderdale where he met Gelfand and observed with some disbelief his no-handed maneuver. By 1978 the Ollie Air was born, known today simply as the ollie.
After Peralta formed Powell Peralta with George Powell, Gelfand was recruited as the first member of the new team by Stacey Peralta. This team later became known as the Bones Brigade and came to include other Florida skaters of the 70s such as Mike McGill, inventor of the 540 aerial or "McTwist" in 1984, and Rodney Mullen who during the 1980s helped foster the ollie for use on flat ground. Tony Hawk would be another Bones Brigade member to benefit from the ollie. On vert he used the maneuver as a way to achieve higher air when doing tricks. By the mid-1980s Alan Ollie Gelfand maneuver had transformed trick skating in its three disciplines of vert, freestyle and street. Most skateboard tricks today in street skating are now based on this maneuver.
