Bosc Pear  The origin is in dispute. One view is it originated in Belgium, but Andre Leroy in his Dictionare Pomologie of 1867 says it is of French origin, named in honor of Louis Bosc, an eminent French horticulturist.  Robert Manning and William Kenrich introduced the variety into the United States in 1832.  The variety was catalogued by the American Pomological Society at its first meeting in 1848.
