“In 1919 Laurence was appointed to the Board of Directors at Cadbury’s as a Managing Director, and following the death of his father George Cadbury in 1922 held an increasingly influential role in the business. At that time chocolate was mostly hand made. Laurence was largely responsible for the introduction of automatic production lines, cutting production costs whilst drastically increasing sales. As Chairman from 1944 he oversaw a growth of sales from £14m in 1939 to £85m by his retirement in 1959, whilst at the same time developing the firm from 16,000 employees to 27,000 with international interests in Canada, Australia, New Zealand and South Africa. Laurence went on to hold the position of Chairman longer than anyone except his father.
Laurence Cadbury’s business and economic acumen was recognised by Montague Norman, the Governor of the Bank of England, when he was appointed as a Director of the Bank of England in 1936, a position he held until 1961.”
