It wasn’t until 1954, when Sir Beaver thought back to the argument he and his friends had at the shooting party as an interesting way of settling pub arguments and promoting his Guinness brewery at the same time. He asked twins Norris (1925-2004) and Ross McWhirter (1925-1975) to put together a book of facts and figures. Using an old gymnasium that had been converted into rooms, Sir Beaver opened offices on the top floor of Ludgate House, 107 Fleet Street and incorporated Guinness Superlatives on November 30th. Ross and Norris both were sports journalists in 1950. In 1951, they published Get to Your Marks. Ross McWhirter and his twin brother, Norris were the co-founders of the Guinness Book of Records.
