Karl Grigorovich, also known by the German form Charles Gregorowitsch, was a Russian violinist. He was born on 25 October 1868 in St. Petersburg and died on 25 March 1921 in Vitebsk.
He was the last pupil of Henryk Wieniawski. He also studied in Moscow with Vasily Bezekirsky and in Vienna with Jakob Dont, and subsequently refined his playing in Berlin under Joseph Joachim.
From 1883, Grigorovich toured internationally. In 1896–1897 he undertook a concert tour of the United States, where critics praised his “brilliant ardour and attack” in Joachim’s Variations and his “delightful technique and warmth of understanding” in Max Bruch’s First Violin Concerto. From 1899 to 1901, he made a world tour across America, Asia and Africa with the Finnish pianist Edvard Fazer.
In 1903 he became a professor at the Moscow Philharmonic School. From 1910 he served as first violinist of the Duke of Mecklenburg Quartet. According to Henryk Łachy, the breadth and smoothness of Grigorovich’s tone were compared with those of Soret and Sarasate.
After the revolutionary events of 1917, he lived and worked in Vitebsk, teaching at the city conservatory. His pupil Bronisław Huberman said that Grigorovich had taught him everything a teacher could teach.
