John Charles Walsham Reith, 1st Baron Reith, was a Scottish broadcasting executive who established the tradition of independent public service broadcasting in the United Kingdom. In 1922, he was employed by the BBC, then the British Broadcasting Company Ltd., as its general manager; in 1923 he became its managing director, and in 1927 he was employed as the Director-General of the British Broadcasting Corporation created under a royal charter. His concept of broadcasting as a way of educating the masses marked for a long time the BBC and similar organisations around the world. An engineer by profession, and standing at 6 feet 6 inches (1.98 m) tall, he was a larger-than-life figure who was a pioneer in his field.
