Thomas Tellefsen was born in Trondheim, Norway, where he studied with his father, the organist Johan Christian Tellefsen, and with Ole Andreas Lindeman. Thomas gave his first public concert in his home town at age 18. In the following year he went to Paris, where he became the pupil of his compatriot Charlotte Thygeson, and later attended some of Friedrich Kalkbrenner´s classes. During the years 1844 to 1847 he was taught periodically by Frédéric Chopin, who also became his personal friend and had considerable influence on his musical taste, style of playing and compositions.
After an extremely successful Paris début in 1851, Tellefsen soon became regarded as one of the outstanding pianists of his time, and was especially admired as an interpreter of Chopin's music. When Chopin died in 1849, Tellefsen also took over some of his teacher's pupils, including Jane Stirling. In the 1850s and 1860s, Tellefsen was regarded as a very successful pianist, and he toured several times to England, Sweden and Norway. He died in Paris, and is buried at the Cimetière d´Auteuil.
