The Hells Angels Motorcycle Club (HAMC) is a worldwide one-percenter motorcycle club whose members typically ride Harley-Davidson motorcycles. In the United States and Canada, the Hells Angels are incorporated as the Hells Angels Motorcycle Corporation. Common nicknames for the club are the "H.A.", "Red & White", "HAMC", and "81". With a membership of between 3,000 and 3,600 and 467 charters located in 59 countries, the HAMC is the largest motorcycle club in the world. The Hells Angels originated on March 17, 1948, in Fontana, California, when several small motorcycle clubs agreed to merge. Otto Friedli, a World War II veteran, is credited with starting the club after breaking from the Pissed Off Bastards motorcycle club over a feud with a rival gang. According to the Hells Angels' website, the club’s name was first suggested by an associate of the founders named Arvid Olsen, who had served in the "Hell's Angels" squadron of the Flying Tigers in China during World War II. It is at least clear that the name was inspired by the tradition from World Wars I and II whereby the Americans gave their squadrons fierce, death-defying titles; an example of this lies in one of the three P-40 squadrons of Flying Tigers fielded in Burma and China, which was dubbed "Hell's Angels". In 1930, the Howard Hughes film Hell's Angels showcased extraordinary and dangerous feats of aviation, and it is believed that the World War II groups who used that name based it on the film. According to the Hells Angels' website, they are aware that there is an apostrophe missing in "Hell's", but state that, "...it is you who miss it. We don't". Some of the early history of the HAMC is not clear, and accounts differ. According to Ralph "Sonny" Barger, founder of the Oakland charter, early charters of the club were founded in San Francisco, Gardena, Fontana, Oakland and elsewhere, with the members usually being unaware that there were other clubs. One of the lesser-known clubs existed in North Chino/South Pomona, in the late 1960s. Other sources claim that the Hells Angels in San Francisco were organized in 1953 by Rocky Graves, a Hells Angel member from San Bernardino ("Berdoo"), implying that the "Frisco" Hells Angels were very much aware of their forebears. The "Frisco" Hells Angels were reorganized in 1955 with thirteen charter members, Frank Sadilek serving as president, and using the smaller, original logo. The Oakland charter, at the time headed by Barger, used a larger version of the "Death's Head" patch nicknamed the "Barger Larger", which was first used in 1959. It later became the club standard.[citation needed] The first chapter to open outside California was established in Auckland, New Zealand, in 1961. The Hells Angels are often depicted in semi-mythical romantic fashion like the 19th-century James–Younger Gang: free-spirited, iconic, bound by brotherhood and loyalty. At other times, such as in the 1966 Roger Corman film The Wild Angels, they are depicted as violent and nihilistic, little more than a violent criminal gang and a scourge on society. The club became prominent within, and established its notoriety as part of the 1960s counterculture movement in San Francisco's Haight-Ashbury District, playing a part at many of the movement's seminal events. Members were directly connected to many of the counterculture's primary leaders, such as Ken Kesey and the Merry Pranksters, Allen Ginsberg, Jerry Garcia and the Grateful Dead, Timothy Leary, The Beatles, The Rolling Stones, Mick Farren, and Tom Wolfe. Writing a book about the club launched the career of "Gonzo" journalist Hunter S. Thompson. From 1968-69 the Hells Angels of San Francisco headquarters was at 715 Ashbury (across from the Grateful Dead house at 710 Ashbury). The HAMC acknowledges more than a hundred charters spread over 29 countries. The Hells Angels motorcycle club founded a charter in Auckland, New Zealand, in 1961 and has since taken over gangs in Whanganui. New Zealand had the first charter of the Hells Angels outside the United States.Europe did not become widely home to the Hells Angels until 1969 when two London charters were formed. The Beatles' George Harrison invited some members of the HAMC San Francisco to stay at Apple Records in London in 1968. According to Chris O'Dell, only two members showed up at Apple Records, Frisco Pete and Bill "Sweet William" Fritsch.[68] Two people from London visited California, "prospected", and ultimately joined. Two charters were issued on July 30, 1969; one for "South London"—the re-imagined charter renewing the already existing 1950 South London charter—and the other for "East London", but by 1973 the two charters came together as one, called "London". The London Angels provided security at a number of UK Underground festivals including Phun City in 1970 organized by Mick Farren. They awarded Farren an "approval patch" in 1970 for use on his first solo album Mona, which also featured Steve Peregrin Took .
