Felice Togni, fully named Filitz Charles Antonius Togni, was a Dutch violinist and violin teacher. He was born in Zwolle on 3 October 1871, the eldest son of umbrella maker Anton Albertus Felix Simonius Togni and Anna Maria Hubertina de France. His father also dealt in string instruments, violins, bows and related goods, and Togni encountered music at an early age. In 1901 he married Maria Bertha Helene Kretzschmar of Essen.
His first violin teacher was André van Riemsdijk, who had studied at the Liège Conservatory and became a music teacher in Zwolle. Togni subsequently studied with Heynsberg, Richter, L. Kramer, Christiaan Timmner and Willem Kes. He began appearing in concerts in the late 1880s; after a June 1889 concert in Meppel with Jacobus Cornelis van Apeldoorn, a reviewer described him as an experienced violinist with a steady hand, excellent purity of intonation and refined bowing.
From 1892, succeeding Isaäc Troostwijk, until 1917 Togni was associated with the Concertgebouw Orchestra. He began as a first violinist and, two years later, became leader of the second violins, calling himself concertmaster of that section. He was also connected with Kes's orchestra school. He experienced the 1895 transition to Willem Mengelberg and made his only solo appearance with the orchestra in 1894, while Kes was still its conductor.
Togni taught at the Amsterdam Music School of the Society for the Promotion of Music before his appointment in 1914 as principal teacher of violin, quartet playing and violin pedagogy at the Amsterdam Conservatory. His pupils included Gerard Boedijn, Sem Dresden, Jan Felderhof, Cor Kint, Joachim Röntgen, Nap de Klijn and Leon Sametini. He also served for a time on the board of the Royal Netherlands Society of Musicians.
His instructional publications included The Training of the Left Hand, The First Development of Left-Hand Technique, The Mechanism of Double Stopping on the Violin, and The Development of Violin Playing and Violin Making. In his final years he lived with his wife and son on Julianalaan in Overveen. He became ill while attempting to board a tram at Stationsplein in Haarlem and died of a heart attack on 31 October 1929. He was buried at the Roman Catholic Cemetery in Overveen.
