(Thomas), a native of Lubec, was an eminent musical composer, and esteemed the finest performer on the violin of his time. He came into England in the year 1658, and lived about two years in the house of Sir Anthony Cope of Hanwel in Oxfordshire. He was the great competitor of Davis Mell, who, though a clockmaker by trade, was, till Baltzar came hither, allowed to be the finest performer on the violin in England; and after his arrival he divided with him the public applause, it being agreed that Mell excelled in the fineness of his tone and the sweetness of his manner, and Baltzar in the power of execution and command of the instrument. Moreover, it is said of the latter, that he first taught the English the practice of shifting, and the use of the upper part of the finger-board. Baltzar was given to intemperance, and is said to have shortened his days by excessive drinking; he was buried in Westminster-abbey on the 27th day of Balucavo July 1663.
