Lambert originated as a seedling under a Napoleon tree which was planted by the late Henderson Lewelling[80] about 1848 in the orchard of J. H. Lambert, Milwaukee, Oregon. This seedling, supposed to have been a cross between Napoleon and Black Heart, was grafted to May Duke and later transplanted. About 1880, the top died and a sprout from the seedling stock formed a new top. Mr. Lambert gave the new variety his name and in 1895 turned over his stock to the Oregon Horticultural Society with the exclusive right to propagate. The variety was placed on the fruit list of the American Pomological Society in 1899 where it still remains.
