Some context: Luzzatti was born of Jewish parents in Venice on 11 March 1841. After completing his studies in law at the University of Padua, he attracted the attention of the Austrian police by his lectures on political economy, and was obliged to emigrate after starting a mutual aid society among gondoliers. In 1863 he obtained a professorship at the Milan Technical Institute; in 1867 he was appointed professor of constitutional law at Padua, whence he was transferred to the University of Rome. Gifted with eloquence and energy, he popularized the economic ideas of Franz Hermann Schulze-Delitzsch in Italy, worked for the establishment of a commercial college at Venice, and contributed to the spread of people's banks on a basis of limited liability throughout the country.
He was minister of agriculture in the second Sonnino Cabinet (December 2, 1909 - March 21, 1910), and on the resignation of the latter was called upon to form a cabinet himself. His administration, which lasted until March 18, 1911, was not very successful and fell over a proposed electoral reform. Although a man of first-class financial ability, great honesty and wide culture, he had not the strength of character necessary to lead a government: he showed lack of energy in dealing with opposition and tried to avoid all measures likely to make him unpopular. Furthermore, he never realized that with the chamber, as it was then constituted, he only held office at Giolitti's good pleasure. During the First World War, he was consistently pro-Ally and strongly supported Italian intervention, but his tone was on the whole pessimistic. Although he did not take office while the war lasted, he was always consulted on all financial matters, and his sound advice was generally followed. He became treasury minister in the second incarnation of the Nitti cabinet (March 12 - May 10, 1920), but did not resume office in the third. At the general elections of May 1921, he decided not to stand for parliament again, and was made a senator. In spite of his advanced age, he continued to write on economic and financial problems with his accustomed lucidity and soundness of judgment, insisting on the necessity for Italy to return to free trade and to reduce government interference in business matters to a minimum.
When did he become the treasury minister?
A: March 12 -

Some context: Dimitri Zinovievich Tiomkin (May 10, 1894 - November 11, 1979) was a Russian-born American film composer and conductor. Classically trained in St. Petersburg, Russia before the Bolshevik Revolution, he moved to Berlin and then New York City after the Russian Revolution. In 1929, after the stock market crash, he moved to Hollywood, where he became best known for his scores for Western films, including Duel in the Sun, Red River, High Noon, The Big Sky, Gunfight at the O.K. Corral, and Last Train from Gun Hill. Tiomkin received twenty-two Academy Award nominations and won four Oscars, three for Best Original Score for High Noon, The High and the Mighty, and The Old Man and the Sea, and one for Best Original Song for "The Ballad of High Noon" from the former film.
Tiomkin received his first break from Columbia director Frank Capra, who picked him to write and perform the score for Lost Horizon (1937). The film gained significant recognition for Tiomkin in Hollywood. It was released the same year that he became a naturalized U.S. citizen. In his autobiography, Please Don't Hate Me! (1959), Tiomkin recalls how the assignment by Capra forced him to first confront a director in a matter of music style: [H]e gave me the job without reservation. I could write the score without interference, and he would hear it when it was done. Lost Horizon offered me a superb chance to do something big... I thought I might be going a little too far in the matter of expense, and went to Frank one day as he sat in the projection room [and explained the score.]... He looked shocked. "No, Dimi, the lama is a simple man. His greatness is in being simple. For his death the music should be simple, nothing more than the muttering rhythm of a drum." "But Frank, death of lama is not ending one man, but is death of idea. Is tragedy applying to whole human race. I must be honest. Music should rise high, high. Should give symbolism of immense loss. Please don't hate me." He worked on other Capra films during the following decade, including the comedy You Can't Take It With You (1938), Mr. Smith Goes to Washington (1939), Meet John Doe (1941), and It's a Wonderful Life (1946). During World War II, he continued his close collaboration with Capra by composing scores for his Why We Fight series. These seven films were commissioned by the U.S. government to show American soldiers the reason for United States participation in the war. They were later released to the general U.S. public to generate support for American involvement. Tiomkin credited Capra for broadening his musical horizons by shifting them away from a purely Eurocentric and romantic style to a more American style based on subject matter and story.
