Life with Boswell:
Boswell met "Quanten, a Swede, an officer in the service of Brunswick" who "was kind enough to entertain [him] with some music this morning" on August 17, 1764 in Brunswick. The Swede also told Boswell about several of Boswell's kin, whose ancestors had emigrated to Sweden in the 17th century. Boswell described Quanten as follows:
"He plays delightfully on the German flute, and composes very well in a singular taste, with quick transitions from high to low notes, very hard to play. He paints too. He is a lively, genteel, brisk young man. He brought to my mind many ideas of healthy, accomplished foreign officers."
