Jonathan Hayne
Jonathan Hayne (1810 - 1848) was born in Clerkenwell, London, son of a surgeon. He apprenticed as a silversmith and started his career in 1810, entering his mark in partnership with Thomas Wallis, at 16 Red Lion Street, Clerkenwell. Six years later, Wallis and Hayne dissolved their partnership. In 1821, Jonathan entered his own first mark.
In 1833, Hayne increased his popularity, patenting a method of manufacturing silver spoons and cutlery in a single blow thanks to a heavy hammer. This method was illustrated in 1839 in "A Dictionary of Arts, Manufactures, and Mines" by Andrew Ure.
In 1836, Jonathan Hayne’s son, Samuel, went into partnership with Dudley Frank Cater and they entered their mark as Hayne & Cater. Samuel assumed the full control of the company after his father’s death in 1848 and continued trading until 1865, when he declared bankruptcy.
