Thomas and Howard Grubb, father and son, made telescopes in Dublin from c.1830 to 1925. The elder Grubb's first telescopes of some size were the 1835 equatorial mounting of a 34-cm Cauchoix objective for E. J. Cooper of Markree Castle, Co. Sligo, Ireland, and a 15-inch reflector for Armagh Observatory (1840), which employed a centrifugal governor and the first mirror-cell with rocking support pads. The firm continued in Newcastle-upon-Tyne in England as Sir Howard Grubb, Parsons and Co.
