Lazăr was born in Craiova, Romania and died in Paris, France. At the Bucharest Conservatory (1907-1912) he studied piano with Emilia Saegiu, theory with Dumitru Georgescu Kiriac and with Alfonso Castaldi he studied harmony, counterpoint and composition. He studied for two years with Castaldi at the Leipzig Conservatory before touring as a pianist, playing much new music. From 1928 he was in France and Switzerland. He ventured from a Romanian nationalistic style into serialism and neo-classicism.
From 1925, important publishers in Paris (Durand, Salabert, Max Eschig and Heugel) and Vienna (Universal Edition) began printing the works of Lazǎr and other Romanian composers such as Mihail Jora, Marcel Mihalovici and George Enescu.
In 1920 Lazăr was a founder-member of the Society of Romanian Composers. In 1932, along with Mihalovici, he was among the founders of the Triton society of contemporary music in Paris (1932-1939), and a member of its active committee.
