Thomas Cooke (8 March 1807 – 19 October 1868) was a British instrument maker based in York. He founded T. Cooke & Sons, the instrument company

Life[edit]

Thomas Cooke was born in Allerthorpe, near Pocklington, East Riding of Yorkshire, the son of James Cook (a shoemaker).[1][2]

His formal education consisted of two years at an elementary school (possibly the school of John Whitaker, also of Allerthorpe),[1] but he continued learning after this and he taught himself navigation and astronomy with the intention of becoming a sailor. His mother dissuaded him from that career and in 1829 he moved to York and worked as a mathematics schoolmaster at the Rev. Schackley's School in Ogleforth,[3] near York Minster. He also taught in various ladies' schools to increase his income.

His marriage to Hannah was to produce seven children, five of whom were boys. Two of these Charles Frederick (1836–98) and Thomas (1839–1919) subsequently joined him in the business he founded in 1836 at number 50 (now renumbered to 18) Stonegate, close to York Minster with the assistance of a loan of £100 from his wife's uncle.

Cooke studied optics and became interested in making telescopes, the first of which was a refracting telescope with the base of a tumbler shaped to form its lens. This led to his friends including John Phillips encouraging him to make telescopes and other optical devices commercially.[4][5][6]

Work[edit]

In 1837 he established his first optical business in a small shop at 50 Stonegate, York, and later moved to larger premises in Coney Street. He built his first telescope for William Gray. At that time, the excise tax on glass discouraged the making of refracting telescopes, which were usually imported from abroad. Cooke was thus one of the pioneers of making such telescopes in Britain.

He made more instruments and built his reputation. He was not only an optician but had mechanical abilities as well, and among other things, manufactured turret clocks for church towers. He founded the firm T. Cooke & Sons. In 1855 he moved to bigger premises, the Buckingham Works at Bishophill in York, where factory methods of production were first applied to optical instruments.[7] He exhibited at the York Exhibition in 1866 demonstrating his three-wheeled, steam powered car which he claimed could carry 15 people at 15 mph for a distance of 40 miles.[8]

One of his finest achievements was the construction of the 25-inch 'Newall' refractor for Robert Stirling Newall; sadly, Thomas died before seeing it completed. For some years the Newall was the largest refracting telescope in the world.[9] On Newall's death it was donated to the Cambridge Observatory and finally moved in 1959 to Mount Penteli observatory in Penteli, Greece. He made a telescope for the Royal Observatory, also Greenwich and another for Prince Albert. The firm amalgamated with Troughton & Simms (London) to become Cooke, Troughton & Simms in 1922 and this later became part of Vickers, but still run by his sons Thomas & Frederick.

Thomas Cooke was succeeded by his sons, Thomas and Frederick. He is buried in York Cemetery.

Telescopes in use today[edit]

  • A telescope made by Thomas Cooke is still in daily use at Carter Observatory – The National Observatory of New Zealand, delivering excellent results. The original 9-inch triplet lens has been replaced by a 9 1/2 doublet made by renowned optician Garry Nankivell.
  • A 5" refractor dating from 1880 is still in regular use at Clanfield Observatory, Hampshire.[10]
  • A 6.5" refractor manufactured in 1870 is in use at the Assheton Observatory at Rossall School.
  • An 8" refractor is housed in the Jeremiah Horrocks Observatory, Moor Park, Preston, Lancashire.
  • The Fry telescope,[13] an 8" refractor manufactured in 1862, is in regular use at the University of London Observatory[14] in Mill Hill, London.
  • A 10" refractor from 1860 is in use at the Blackett Observatory, Wiltshire.[15]
  • A 10" refractor from 1871, which was purchased by St. Andrews in 1938 and used as a training telescope, has been in use since 1951 at Mills Observatory, Dundee, Scotland.
