Howard Grubb

He is also noted for his work to perfect the periscope and inventing the reflector sight.

Sir Howard Grubb perfected the device in World War I. Morgan Robertson (1861–1915) claimed to have tried to patent the periscope: he described a submarine using a periscope in his fictional works.

Howard Grubb was one of eight children of Thomas, founder of the Grubb Telescope Company so Howard developed an early interest in optics.

Thomas Grubb was joined in 1864 by his son Howard who built on the company's reputation for quality optical instruments.

He is also noted for his work to perfect the periscope and inventing the reflector sight. In 1900 Grubb invented the reflector or "reflex" sight, a non-magnifying optical sight that uses a collimator to allow the viewer looking through the sight to see an illuminated image of a reticle or other pattern in front of them that stays in alignment with the device the sight is attached to (parallax free).

The idea of a reflector sight originated in 1900 with Irish optical designer and telescope maker Howard Grubb in patent No.12108.

Some of the telescopes produced by Howard Grubb include the 27-inch refractor for the Vienna Observatory (1878), the 10-inch refractor at Armagh Observatory (1882), the 28-inch refractor at the Royal Observatory, Greenwich – the UK's largest refractor (1893), and the 10-inch refractor at Coats Observatory, Paisley (1898).

As well as the everyday visitor there are many notable guests, such as William Speirs Bruce, the leader of the Scottish National Antarctic Expedition from 1902 to 1904; Howard Grubb, telescope maker; David Gill, Her Majesty's Royal astronomer at the Cape Observatory in South Africa from 1879 to 1907; Frank Watson Dyson, Astronomer Royal of England from 1910 to 1933; and Keir Hardie, one of the founders of the Labour Party.

Their youngest son was Sir Howard Grubb, who took over the optical business.

It also houses the astronomical instruments used to make meridian observations and the 28-inch equatorial Grubb refracting telescope of 1893, the largest of its kind in the UK.

Sir Howard Grubb (28 July 1844 – 16 September 1931) was an optical designer from Dublin, Ireland.

He was head of a family firm that made large optical telescopes, telescope drive controls, and other optical instruments.

Grubb was elected Fellow of the Royal Society in 1883 and of the Royal Astronomical Society in 1870.

In 1887 he was knighted by Lord Lieutenant at Dublin castle.

Sir Howard was a longtime member of the Royal Dublin Society, serving as Honorary Secretary from 1889 to 1893, and as Vice-President from 1893 to 1922.

Under Howard Grubb the Grubb Telescope Company gained an even greater reputation for quality optical instruments.

Grubb was also known for building accurate electrically driven clock drives for equatorial mounted telescopes.

In 1887 Grubb's firm built seven normal astrographs for the Carte du Ciel international photographic star catalogue project, 13-inch refracting telescopes all designed to produce uniform photographic plates.
