Introducing "LEO" - The Electronic Office.
Science Comes to the Aid of the Industrial Office Worker.
Less than one hour to calculate and record the wages of 1700 men both individually and collectively; invoicing and cost accounting in a mere fraction of the time normally taken by human methods. Achievements like this are now a regular feature at a large London undertaking which employs 32,000 people (2,800 clerks) (J. Lyons Ltd. Cadby Hall). On its own account the Electronics Dept of the firm, working with the Comptroller of the Accounts department, has developed the first all-purpose commercial electronic high speed calculator ever built anywhere in the world. Called "LEO", it is not just another electronic brain. It is basically an electronic calculator, but means have been perfected of feeding the machine with information as fast as it can absorb it and at the other end, of recording results in printed form just as fast as the machine can produce them. Any commercial office work involving repetitive calculation is within its scope, and with it clerks can look forward to a new era, free from arithmetical drudgery, in which they can be concerned far more with the interesting task of interpreting figures rather than producing them. Six years of research have gone into LEO which has a surprising versatility. Already it has done work for insurance people, on guided missiles and other such calculations. More than 5,000 valves were used in the construction and dozens of miles of wiring. Operation is simple, and control possible at all stages. This is a pictures from a series showing various aspects of LEO.
