Born in Florence, Tofanari after studying sculpture at the Accademia di Belle Arti moved to Paris and successively to London where he perfected his technique. An insightful observer of nature, Tofanari was famous for his ability to carve animals in their particular gait and to catch the naturalness of his subjects thanks to his chiselling prowess. He took part from 1909 to 1934 in all editions of the Venice Biennale, while in the Rome Quadriennale an entire pavilion was dedicated to him. His works can be admired in keynote galleries both in Italy and abroad: Rome, Florence, Paris, London, Brussels, Amsterdam, Buenos Aires, Bahia Blanca, Santa Fe, Rio de Janeiro, San Paolo.
In 1949, the President of the Republic issued a decree appointing him a member of the Accademia of San Luca in Roma.
