Allen & Overy Corporation Short History

The law firm was founded on January 1, 1930, by George Allen and Thomas Overy. Both Allen and Overy were partners at another law firm called Roney & Co. With the goal to establish a commercial practice and with Allen’s experience in guiding King Edward VIII during the 1936 abdication, the company gained quite a reputation in the field.

In 1939, the company became one of the leading law firms in the city. Throughout the years, the law firm has been involved in numerous cases, such as handling the hostile takeover of London, Eurobond transactions, and more.
