Talbot

Talbot was an automobile marque that existed from 1903 to 1994, with a hiatus from 1960 to 1978, under different owners, latterly Peugeot. Talbot participated in rallying, winning the 1981 World Rally Championship constructors' title, and in Formula One.

Inception of the British Talbot

Talbot was originally the British marque used to sell imported French Clément-Bayard cars. Founded in 1903, this business venture was financed by Charles Chetwynd-Talbot, 20th Earl of Shrewsbury and Adolphe Clément-Bayard.

Starting in 1905, the company sold imported cars under the Clément-Talbot marque and began assembling French-made parts at a new factory located in Barlby Road, Ladbroke Grove, North Kensington, London, selling them under the name Talbot after the first year. Domestically-designed cars followed from 1906. By 1910, 50 to 60 cars a month were being made.

A Talbot was the first car to cover 100 mi (160 km) in one hour, in 1913.

Construction of the Clement Talbot Motor Works began in 1903 on a North Kensington site bought in October 1902. It was UK's first purpose-built car factory. The initial building, a large flexible open space, is known today as Ladbroke Hall. Subsequent works additions have been demolished and redeveloped.

Talbot (crater)

Talbot is a small lunar crater on the Mare Smythii, near the eastern limb of the Moon. It lies between a pair of larger, flooded craters, with Runge to the west and Haldane to the west-northwest. The crater is entirely surrounded by the dark lunar mare. It is a circular, bowl-shaped formation with an almost featureless interior floor. The outer rim has a slightly higher albedo than the surrounding terrain, but the floor is as dark as the mare.

Lumen second

In photometry, the lumen second (lm s or lm⋅s) is the SI derived unit of luminous energy. It is based on the lumen, the SI unit of luminous flux, and the second, the SI base unit of time.

The lumen second is sometimes called the talbot (symbol T). This name was coined in 1937 by the Committee on Colorimetry, Optical Society of America, in honor of the early photographer William Fox Talbot. The talbot is exactly equal to the lumen second:

The use of the symbol T for talbots conflicts with T as the symbol for the tesla, the SI unit of magnetic flux density.

An older name for the lumen second was the lumberg.

The photometric unit lumerg, also proposed by the Committee on Colorimetry in 1937, correlates with the old CGS unit erg in the same way that the lumen second correlates with the radiometric unit joule, so that 10⁷ lumerg = 1 lm⋅s.
