Goldsmid was the son of Frederick Goldsmid and his wife Caroline Samuel. His father was a banker and Member of Parliament for Honiton. Goldsmid was educated privately until he entered University College, London. In 1864 he became a fellow of University College, and was also called to the bar. After a brief period on the Oxford circuit, he gave up practicing law when he was elected to parliament.
Goldsmid was first stood for Parliament at a by-election in February 1864 for the borough of Brighton, without success, and he was defeated again at the 1865 general election, when he contested Cirencester. He was elected unopposed as a Member of Parliament (MP) for Honiton at a by-election in March 1866. In that year, Goldsmid inherited Somerhill House near Tonbridge, Kent, on the death of his father. Honiton was disfranchised in 1868 by the Reform Act of 1867 and at the 1868 general election Goldsmid stood unsuccessfully for Mid Surrey. He was elected for Rochester at a by-election in 1870 and held the seat until his defeat at the 1880 general election. In 1879, Goldsmid began expanding Somerhill to accommodate his large family - he had eight daughters. The work took until 1897 to complete.
He then contested a by-election in May 1880 for Sandwich, and was returned to the Commons after a five-year absence at the 1885 general election as MP for St Pancras South, holding that seat until his death in 1896. In 1894 Goldsmid was deputy Speaker of the House of Commons.
In 1878 Goldsmid succeeded his uncle, Sir Francis Goldsmid to the baronetcy and to the estate of Whiteknights Park at Earley in Berkshire, as well as others in Sussex, Kent and elsewhere. He also bore the Portuguese title of Baron de Goldsmid e da Palmeira. His business interests included being chairman of the Submarine Telegraph Company and the Imperial and Continental Gas Association, and he was a director of the London, Brighton, and South Coast Railway. A steam locomotive was named Goldsmid after him in 1892.
Goldsmid was treasurer of University College in 1880-81 and was a member of the council of University College Hospital. He was vice-chancellor of the University of London when he died. He was Deputy lieutenant of Kent, Sussex, and Berkshire, J. P. for Kent, Sussex, and London, colonel of the 1st Sussex Rifle Volunteers, and honorary colonel of the 1st Sussex Artillery Volunteers.
In 1868 Goldsmid married Virginia Philipson of Florence and had eight daughters.
