Frederick Katz (February 25, 1919 – September 7, 2013) was an American cellist and composer.[1] He was among the earliest jazz musicians to establish the cello as a viable improvising solo instrument.[2] Katz has been described in CODA magazine as "the first real jazz cellist."[3] Cellist Fred Lonberg-Holm (b. 1962), who recorded a 2002 tribute album to the older musician (A Valentine For Fred Katz, Atavistic Records), praises Katz for introducing his instrument to jazz: "[Katz] managed to find a way to make it swing.
