The Yard-O-Led Pencil Company was founded in London, England in 1934 by a Mr Brenner to produce his patent propelling pencils which contained twelve three inch leads (that is to say, 36 inches or a yard of lead). After the Second World War the company merged with Sampson Mordan Ltd whose founder had patented the first mechanical pencil in 1822. They built a new factory in Birmingham and took over Edward Baker Ltd, another pencil maker.
