From Wikipedia, the free encyclopedia
Sir Howard Grubb, Parsons and Co. Ltd. was a telescope manufacturer more commonly known as Grubb Parsons. Based in Newcastle upon Tyne it was originally founded in Dublin by Thomas Grubb as the Grubb Telescope Company. Thomas Grubb was joined in 1964 by his son Howard who built on the companies reputation for quality optical instruments. In 1925 the company was aquired by Sir Charles Parsons and renamed. The company traded until 1985, designing and building the optical components for telescopes such as the Anglo-Australian Telescope, the Isaac Newton Telescope and the William Herschel Telescope, all of which are important astronomical instruments currently in use.[1]
