Emile Beaumont d'Erlanger
Baron Emile Beaumont D'Erlanger  (4 June 1866 – 24 July 1939) was a French-born British merchant banker.

Life

He was the second eldest son of Frédéric Emile d'Erlanger, a banker working in Paris at the French branch of Emile Erlanger and Company and Marguerite Mathilde Slidell (1842–1927). (See: Erlanger family tree).

His older brother, Baron Raphael Slidell d'Erlanger, who might have been more likely to follow his father into banking, was instead a scientist and professor at Heidelberg. Emile followed the banking route and from his father he was entrusted with presidency of the railway and tramway companies including the New General Traction Company in England.

In 1891 he became a naturalised British subject.

From 1911 he was chairman of the Channel Tunnel Company (the predecessor of EuroTunnel) and financed its design.

The company also financed the building of railways in Rhodesia, Angola and the Congo.
