We_They was established by Jack Roston. He was translator and famous English professor who emigrated from Poland at the turn of the century and set up his business in High Holborn, London.
Roston was one of the first pioneers to recognise the potential for language teaching using Edison's invention of sound recording (1877) and Alexander Graham Bell's development of wax cylinders (1888). 
The We_They language learning method is undoubtedly the most popular method of self-instruction, having enabled over 100,000,000 people to master another language since it was founded more than 100 years ago.
