Adolphe Sax
Antoine-Joseph Sax was born on 6 November 1814, in Dinant, in what is now Belgium, to Charles-Joseph Sax and his wife. While his given name was Antoine-Joseph, he was referred to as Adolphe from childhood. His father and mother were instrument designers themselves, who made several changes to the design of the French horn. Adolphe began to make his own instruments at an early age, entering two of his flutes and a clarinet into a competition at the age of 15. He subsequently studied performance on those two instruments as well as voice at the Royal Conservatory of Brussels.
Adolph Joffe
Adolf Abramovich Joffe was born in Simferopol, Crimea, Russian Empire in a wealthy Karaite family. He became a social democrat in 1900 while still in high school, formally joining the Russian Social Democratic Labor Party in 1903. In 1904 Joffe was sent to Baku, which he had to flee to avoid arrest. He was then sent to Moscow, but had to flee again, this time abroad. After the events of Bloody Sunday on January 9, 1905, Joffe returned to Russia and took an active part in the Russian Revolution of 1905. In early 1906 he was forced to emigrate and lived in Berlin until his expulsion from Germany in May 1906.
