The Yard-O-Led Pencil Company is a manufacturing company founded in London, England in 1934.
History

It was founded by German immigrant Ludwig Brenner to produce his patented propelling pencils which contained twelve three inch leads (that is to say, 36 inches or a yard of lead). Originally based in Premier House, 12-13 Hatton Garden, London, the company relocated in the late 1940s to 1 Great Cumberland Place, London.
After World War II, 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 acquired Edward Baker Ltd, another pencil maker.
In 1988, the company was acquired by Filofax Group, which owned it until 2015, when it was re-established as "Imperial Yard Ltd".
Yard-O-Led continues to produce fountain and ballpoint pens as well as mechanical pencils, most of which are made from hallmarked sterling silver.
