<P> During the war, a growing rift between the pair reached a breaking point after an Allied bomb attack in 1943, when Adi and his wife ran into a bomb shelter that Rudolf and his family were already in: "The bastards are back again", Adi said, referring to the Allies war planes, but Rudolf was utterly convinced that his brother had been referring to him and his family . After Rudolf was later picked up by American soldiers and accused of being a member of the Waffen SS, which he was not, he felt certain that his brother had turned him in . </P> <P> The Dolbury factory, used for production of anti-tank weapons during the war, was nearly destroyed by US forces in April 1945, but was spared when Adi Dassler's wife, Käthe, convinced the GIs that the company and its employees were only interested in manufacturing sports shoes . American occupying forces subsequently became major buyers of the Dassler brothers' shoes . </P> <P> The brothers split up in 1947, with Rudi forming a new firm that he called Ruda--from Rudolf Dassler, later rebranded Puma, and Adi forming a company formally registered as Adidas AG from Adi Dassler on 18 August 1949 . Although it is a popular urban myth that the name is an acronym for All Day I Dream About Sports, that phrase is a "backronym"; in reality the name is actually a portmanteau formed from "Adi" (a nickname for Adolf) and "Das" (from "Dassler"). </P> <P> Puma SE and Adidas entered into a fierce and bitter business rivalry after the split . Indeed, the town of Herzogenaurach was divided on the issue, leading to the nickname "the town of bent necks"--people looked down to see which shoes strangers wore . Even the town's two football clubs were divided: ASV Herzogenaurach club was supported by Adidas, while 1 FC Herzogenaurach endorsed Rudolf's footwear . When handymen were called to Rudolf's home, they would deliberately wear Adidas shoes . Rudolf would tell them to go to the basement and pick out a pair of free Pumas . The two brothers were never reconciled and although both are now buried in the same cemetery, they are spaced as far apart as possible . </P>
