During a grouse hunting party four years earlier, the managing director of the brewery Sir Hugh Beaver became involved with a shooting companion over the identity of the fastest game bird in the region—owing to his having missed his quarry ostensibly—and realising that there was no easy way of settling this debate without recourse to experts saw an immediate niche in the reference book market. 
Beaver employed a London fact-finding agency run by brothers Norris and Ross McWhirter (both boasting encyclopaedic memories) compiled The Guinness Book of Superlatives and gave away a thousand copies to associates and to bars licensed to serve the beer. Due to its surprise popularity, a two-hundred page edition was bound the following year, released on this day in 1955 and became best-seller in the UK immediately, prompting a second edition before Christmas and entered the international market. Beginning in the early 1970s, the annual began to include record feats of strength and stamina by human individuals as well as facts about the natural world and is considered one of the best-selling books of all time.
