Reference excerpt

J. Lyons & Co. was a British restaurant chain store, food manufacturing, and hotel conglomerate founded in 1884 by Joseph Lyons and his brothers in law, Isidore and Montague Gluckstein. Lyons' first teashop opened in Piccadilly, London in 1894, and from 1909 they developed into a chain of teashops, with the firm becoming a staple of the High Street in the UK. At its peak the chain numbered around 200 cafes. The teashops provided for tea and coffee, with food choices consisting of hot dishes and sweets, cold dishes and sweets, and buns, cakes and rolls. Making their first cakes and pastries in 1894, several Lyons cake products are still available on grocers' shelves, including Lyons' treacle tart, Lyons' Bakewell tart, Lyons' Battenberg, and Lyons' trifle sponges, which are sold by Premier Foods. The company is also known for its pioneering use of computers in the office.

Origins and early history

The company began as a collaboration between a group of entrepreneurs, the professional artist Joseph Lyons and his brothers in law, Isidore and Montague Gluckstein, as a spin off from the Salmon & Gluckstein tobacco company. In 1894 the company started a teashop in Piccadilly, London, and from 1909 developed this into a chain of teashops which would ultimately number around 200 locations. The company also ran high class restaurants, founding the Trocadero in 1895, and hotels including the Strand Palace, opened in 1909, the Regent Palace, opened in 1915, and the Cumberland Hotel, opened in 1933, all in London. In 1918, to increase sales in northern England, Lyons bought the old established tea company Horniman & Sons. From the 1930s Lyons began to develop a pioneering range of teas, biscuits and cakes that were sold in grocery stores across the world. Lyons was appointed to run the company, and it was named after him. J. Lyons & Co. was a pioneer in introducing computers to business. Between 1951 and 1963, the company manufactured and sold a range of LEO (Lyons Electronic Office) computers.

Products and image

The company was a substantial food manufacturer, with factories at Cadby Hall in Hammersmith, and from 1921 at Greenford, producing bread, cakes, pies, tea, coffee and ice cream. Lyons branded cakes included treacle tarts, Lyons Bakewell tart, Lyons Battenberg, and Lyons trifle sponges. To the public, J. Lyons & Co. were best known for their chain of teashops which opened from 1894 and finally closed in 1981, and for the Lyons Corner Houses in the West End of London. The teashops provided for tea and coffee, with hot dishes and sweets, cold dishes and sweets, and buns, cakes and rolls. Lyons' teashops were slightly more up market than their ABC (Aerated Bread Company) competitors. They were notable for their interior design, from the 1920s Oliver P. Bernard being consultant artistic director. Until the 1940s they had a certain working-class chic, but by the 1950s and 1960s they were quick stops for busy shoppers where one could drink a cup of tea and eat a snack or an inexpensive meal. The teashops always had a bakery counter at the front, and their signs, Art Nouveau gold lettering on white, were a familiar landmark. Before the Second World War service was to the table by uniformed waitresses, known as 'Nippies'; after the war the teashops converted to cafeteria service.

Corner Houses

Lyons' Corner Houses, which first appeared in 1909 and remained until 1977, were noted for their art deco style. Situated on or near the corners of Coventry Street, Strand and Tottenham Court Road, they and the Maisons Lyons at Marble Arch and in Shaftesbury Avenue were large buildings on four or five floors, the ground floor of which was a food hall with counters for delicatessen, sweets and chocolates, cakes, fruit, flowers and other products. In addition, they possessed hairdressing salons, telephone booths, theatre booking agencies and at one period a twice-a-day food delivery service. On the other floors were several restaurants, each with a different theme and all with their own musicians. For a time the Corner Houses were open 24 hours a day, and at their peak each branch employed around 400 staff. They featured window displays, and, in the post-war period, the Corner Houses were smarter and grander than the local tea shops. The artist Kay Lipton designed all the windows for the Corner Houses under the supervision of Norman Joseph, the director post-war. Between 1896 and 1965 Lyons owned the Trocadero, which was similar in size and style to the Corner Houses.

Restaurants

As well as the tea shops and Corner Houses, Lyons ran other large restaurants such as the Angel Cafe Restaurant in Islington and the Throgmorton in Throgmorton Street in the City of London. Its chains have included Steak Houses (1961–1988), Wimpy Bars (1953–1976), Baskin-Robbins (1974–present) and Dunkin' Donuts (1989–present).

Hotels The Regent Palace Hotel, Glasshouse Street, London was operated by Strand Hotels Limited, a subsidiary of J. Lyons and Company and opened on 16 May 1915. Strand Hotels also operated the Cumberland Hotel (Marble Arch, London), Kingsley Hotel, Park Court Hotel, Windsor Hotel, White's Hotel and the Strand Palace Hotel after the inception of Strand Hotels Limited. The last London hotel that they operated until the demise of the group in the mid-1970s was the Tower Hotel situated by Tower Bridge in London.

Biscuits company In 1938, Lyons purchased the Bee Bee Biscuit Company, which manufactured biscuits from its factories in Blackpool. Six years later, Lyons changed the company's name to Symbol Biscuits Ltd. and began selling biscuits under the Symbol and Lyons brand names: one of their innovations was Maryland Cookies in 1956. In 1990, Lyons changed the Symbol Biscuits name to Lyons Biscuits Ltd.

Other activities

Supporting the war effort

The rearmament period just before World War II saw a big expansion in the number of Royal Ordnance Factories (ROFs), which were British government-owned. However, due to shortages of management resources some ROFs were run as agency factories; and J. Lyons and Co. ran at least one, ROF Elstow. The management and stock control systems needed in the ROFs, in respect of control of raw materials and "perishable" finished products, were somewhat similar to those used in the catering business; and J. Lyons was ideally suited to this task. They do not appear to have any involvement in managing these after 1945, when the ROFs started to run down.

Worked examples

Example 1 — a first encounter with J. Lyons and Co.

Start with the simplest possible case. Write down what J. Lyons and Co. claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to J. Lyons and Co. before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about J. Lyons and Co. ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of J. Lyons and Co.

In research
J. Lyons and Co. appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses J. Lyons and Co. in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
J. Lyons and Co. is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1884 establishments in England, British brands, British companies established in 1884, so understanding it makes those chapters shorter.
In everyday life
Look for J. Lyons and Co. outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
