Fritz Spindler (24 November 1817 – 26 December 1905) was a German pianist and composer, especially of works for the piano.Born in Wurzbach, Spindler's output of more than 400 opus numbers includes salon pieces, chamber music, symphonies and other large forms, and over 300 piano pieces. But he is best remembered, if at all today, for a much-anthologized sonatina. He published almost 350 compositions.
