Robert Brettel Bate (1782 – 1847) was the son of a prosperous Stourbridge merchant and banker. He first established a workshop in London at 17 Poultry around 1807, followed by 20-21 Poultry in 1824. Bate became a Freeman of the Spectacle Makers Company in 1814 and was Master of the Company in 1828 – 30. In 1818 he was appointed “Optician in Ordinary” to King George IV.
Bate specialized in hydrometers but made a wide range of other instruments including microscopes, telescopes, drawing instruments, sundials, barometers and sextants which may be seen in many museums.
