The Bartlett, (the English name is Williams' Bon Chretien) was found as a wild tree by a Mr. Stair, a school master at Albermaston, Berkshire, England in 1770.  It was acquired from him by Mr. Williams, a nurseryman at Turnham Green, Middlesex, who distributed it.  The ear became known as the Williams and is still known by that name in England and France.  It was brought to America around1797-99 by James Carter of Boston for the Brewer Estate. In  1817, Enoch Bartlett of Dorchester, Mass. became the owner of the estate and, not knowing the true name of the pare, distributed it under his own name.  The American Pomological Society accepted the name Bartlett  let in 1848 and listed the variety in its catalog.
