Roman Hoffstetter (born 24 April 1742, in Laudenbach, near Bad Mergentheim, Germany; died: 21 May (Baker's) or June (New Grove 2nd) 1815, in Miltenberg-am-Main, Germany; alternative spelling Romanus Hoffstetter) was a classical composer and Benedictine monk who also admired Joseph Haydn almost to the point of imitation. Hoffstetter wrote "everything that flows from Haydn's pen seems to me so beautiful and remains so imprinted on my memory that I cannot prevent myself now and again from imitating something as well as I can."In 1965, the musicologist Alan Tyson (with H.C. Robbins Landon) published the finding that the entire set of six String Quartets long-admired as Haydn's Op. 3, including the Andante cantabile of No. 5 in F Major known as Haydn's Serenade, were actually by Roman Hoffstetter. Further discoveries have purported to establish Hoffstetter's authorship of the first two of the six quartets, but not the other four.
