Deputies of Legislature IX of the Kingdom of Italy

Giuseppe Zanardelli (29 October 1826 – 26 December 1903) was an Italian jurist and political figure. He served as the Prime Minister of Italy from 15 February 1901 to 3 November 1903. An eloquent orator, he was also a Grand Master freemason. Zanardelli, representing the bourgeoisie from Lombardy, personified the classical 19th-century liberalism, committed to suffrage expansion, anticlericalism, civil liberties, free trade and laissez-faire economics. Throughout his long political career, he was among the most ardent advocates of freedom of conscience and divorce.

Francesco de Sanctis (28 March 1817 – 29 December 1883) was a leading Italian literary critic and scholar of Italian language and literature during the 19th century.

Silvio Spaventa (12 May 1822 – 20 June 1893) was an Italian journalist, politician and statesman who played a leading role in the unification of Italy, and subsequently held important positions within the newly formed Italian state.

Germain Sommeiller (February 15, 1815, Saint-Jeoire – July 11, 1871) was an Italian civil engineer from Savoy. He directed the construction of the Fréjus Rail Tunnel between France and Italy, also known as the Mont Cenis Tunnel. This was the first of a series of major tunnels built in the late 19th century to connect northern and southern Europe through the Alps. Sommeiller pioneered the use of pneumatic drilling and dynamite to achieve record-breaking excavation speeds. This 12.8-km tunnel was completed on December 26, 1870, 11 years ahead of schedule. It remained the longest tunnel in the world until the opening of the Gotthard Rail Tunnel in 1882.
