Abstract
SIR THOMAS OCTAVIUS CALLENDER, who died at his home at Bidborough Court, Kent, on December 2, at the age of eighty-two years, spent a long and very busy life in promoting the electrical industry. He was the eldest son of the late W. O. Callender of Bournemouth and was born in Glasgow in April 1855. He was educated at Greenock, in London and later at Boulogne-sur-Mer. The outbreak of the Franco-Prussian War made it necessary for him to leave France, and later he entered his father's office in London, devoting himself to the asphalt, paving and bitumen refining business of which W. O. Callender was founder. Having acquired an interest in part of the Trinidad Lake, W. O. Callender and two of his sons founded the business of Callender and Sons, in 1877, for the supply of Trinidad bitumen. Large quantities of bitumen were refined and used for road-making and building purposes, but it was felt that further developments were possible, and its uses for electrical work were constantly considered.
