Lewis H. Lockwood (born December 16, 1930)[1] is an American musicologist whose main fields are the music of the Italian Renaissance and the life and work of Ludwig van Beethoven.
He then did his undergraduate work at Queens College, where his main advisor was the well-known Renaissance scholar, Edward Lowinsky.
He went on to do graduate work at Princeton University in the early 1950s with Oliver Strunk, Arthur Mendel, and Nino Pirrotta.
After a Fulbright scholarship to Italy in 1955–56, he took the Ph.D. in musicology at Princeton with a dissertation on the 16th-century Italian composer, Vincenzo Ruffo, whose sacred music shows the direct influence of the aesthetic of the Counter-Reformation.
[1] Lockwood's work in Italian music history focused first on issues of style and genre, including redefinition of the familiar term "Parody mass" and related subjects.
In 2013, in collaboration with Alan Gosman, he completed seven years of work on the first critical edition of one of the largest and most revealing of the many surviving Beethoven sketchbooks.
The collection includes Beeethoven's annotated copy of the Ninth Symphony and both sketches and the full-score autograph manuscript of the Scherzo of the String Quartet in Eb Major, Op.
