A Dictionary of Music and Musicians/Steffkins, Theodore
STEFFKINS, Theodore, or Theodorus, was a foreign professor of the lute and viol, who resided in London in the latter half of the 17th century. He is much commended in Thomas Salmon's 'Essay to the Advancement of Music,' 1672. His brother, Dietricht, was one of the band of Charles I. in 1641, and his two sons, Frederick and Christian, were famous performers on the viol. They were members of the King's band in 1694, and Christian was living in 1711.
