Sir Thomas Tassell Grant KCB FRS (1795-15 October 1859) was a notable inventor in the 19th century.
He was born in Portsea, Portsmouth, the son of a namesake and his wife Ann (née Tassell) of Soberton, Hampshire.
[1] In 1829 he invented steam-powered machinery for making ship's biscuits that were stamped into hexagonal shapes, thereby ensuring that there was no waste.
[2] In 1834 he invented a desalination plant which distilled fresh water at sea and was described by the Times in 1859 as "the greatest benefit ever conferred on the sailor, materially advancing the sanitary and moral condition of the navy".
The Oxford Dictionary of National Biography remarked, "Despite the marked improvements they bestowed on the quality of the beneficiaries' lives, Grant's inventions were perhaps too homely to receive the mention they deserved in the histories of technology."
