Thomas Cook & Son, originally simply Thomas Cook, was a company founded by Thomas Cook, a cabinet-maker, in 1841 to carry temperance supporters by railway between the cities of Leicester, Nottingham, Derby and Birmingham. In 1851, Cook arranged transport to the Great Exhibition of 1851. He organised his first tours to Europe in 1855 and to the United States in 1866.

In 1865, the founder's son John Mason Cook began working for the company full-time. In 1871, he became a partner, and the name of the company was changed to Thomas Cook & Son. The company was nationalised in 1948, along with the railways, becoming part of the British Transport Commission. After de-nationalisation in 1972, it was acquired by a consortium of Trust House Forte, Midland Bank and the Automobile Association, then subsequently bought by Westdeutsche Landesbank in 1992.

In 2001, it was acquired by the German company C&N Touristic AG, which changed its name to Thomas Cook AG.^[2]

Thomas Cook & Son was founded by Thomas Cook, a cabinet-maker and former Baptist preacher, in 1841, under the name Thomas Cook, to carry temperance supporters by railway between the cities of Leicester, Nottingham, Derby and Birmingham.^[3] The company's first excursion was a one-day rail trip, from Leicester to Loughborough and back; the price of one shilling included a meal. This has been described as the world's first package tour.^[4]

In 1851, the founder arranged transport to the Great Exhibition of 1851. He organised his first tours to Europe in 1855 and to the United States in 1866. In 1865, the founder's son John Mason Cook began working for the company full-time. In 1871, he became a partner, and the name of the company was changed to Thomas Cook & Son.^[5]

Thomas Cook had acquired business premises on Fleet Street, London, in 1865.^[3] The office also contained a shop which sold travel accessories, including guide books, luggage, telescopes and footwear. Thomas saw his venture as both religious and social service; his son provided the commercial expertise that allowed the company to expand. In accordance with his beliefs, he and his wife also ran a small temperance hotel above the office. Their business model was refined by the introduction of the 'hotel coupon' in 1868. Detachable coupons in a counterfoil book were issued to the traveller. These were valid for either a restaurant meal or an overnight hotel stay, provided they were on Cook's list.^[6]

In 1866, the agency organised the first escorted tours of the United States for British travellers, picking up passengers from several departure points. John Mason Cook led the excursion which included tours of several Civil War battlefields. In 1871, a brief but bitter partnership called Cook, Son and Jenkins was formed in the United States with an American businessman.^[7]

The first escorted round-the-world tour departed from London in September 1872. It included a steamship across the Atlantic, a stage coach across America, a paddle steamer to Japan, and an overland journey across China and India.^[3]

In 1873, publication of the quarterly (monthly from 1883) Cook's Continental Timetable began. It continues to be published in 2021, but no longer by Thomas Cook Publishing, which was wound up by its parent company in 2013; the timetable was relaunched in 2014 by an independent company, under the title European Rail Timetable, no longer affiliated with Thomas Cook Group.^[8]

In 1874, Thomas Cook introduced his "circular notes", a product that was originally devised by a London banker in the 1770s and was later superseded by American Express's "traveller's cheques".^[9]

Conflicts of interest between father and son were resolved when the son persuaded his father, Thomas Cook, to retire at the end of 1878. He moved back to Leicester and lived quietly until his death. The firm's growth was consolidated by John Mason Cook and his three sons, especially by its involvement with military transport and postal services for Britain and Egypt during the 1880s when Cook began organising tours to the Middle East.^[10]

In 1884, the British Government attempted to relieve General Gordon from Khartoum. The British army was transported up the Nile by Thomas Cook & Son.^[3]

The company had established offices around the world by 1888, including three in Australia and one in Auckland, New Zealand, and in 1890, the company sold over 3.25 million tickets.^[11] A husband and wife might, for example, pay £85 for a Thomas Cook tour of Germany, Switzerland, and France over six weeks. While expensive enough that the trip would likely be the only one in the couple's lifetime, the company would arrange for a variety of activities new to the middle-class, including museum visits, the opera, and mountain climbing.^[12] John Mason Cook promoted, and even led, excursions to, for example, the Middle East where he was described as "the second-greatest man in Egypt".^[11]
