His name was Sigismund Neukomm before he was knighted, then it became Sigismond Ritter von Neukomm. He was an Austrian composer and pianist.

Neukomm first studied with the organist Weissauer and later studied theory under Michael Haydn, though his studies at Salzburg University were in philosophy and mathematics. He became honorary organist at the Salzburg University church in 1792, and was appointed chorus-master at the Salzburg court theater in 1796.

Neukomm's compositional output is large. With the older composer's approval he made arrangements of Haydn's works, including the oratorios The Seasons and The Creation. He wrote a clarinet quintet, several organ voluntaries, ten operas, incidental music for four plays, 48 masses, 8 oratorios, and a large body of smaller works including vocal pieces, works for piano solo, and about 200 songs.

In 1814 Neukomm was responsible for erecting a tombstone to the memory of Haydn over his first grave in the Hundsturm cemetery in Vienna. The inscription included a puzzle canon composed by Neukomm himself. He had previously been one of Haydn's pupils, and was also in regular contact with the composer in the last months of his life.
