Physicist Etienne Bieler was born in Switzerland and came to Montréal with his family at the age of thirteen. He obtained his B.Sc. in mathematics and physics from McGill in 1915, and during the latter part of the First World War, worked in the Anti-Submarine Division of the British Admiralty. Returning to McGill after the war, Bieler earned an M.Sc. in Physics (1920) and won a scholarship to Caius College, Cambridge, where he joined the Cavendish Laboratory as a research student. There he worked with Sir Ernest Rutherford on the Alpha-particle bombardment of the atom. Bieler's important insights into the laws of force around the atomic nucleus were presented in his Ph.D. thesis (1923). Upon his return to Montréal, Bieler was appointed Assistant Professor of physics at McGill, and developed a new interest in applied geophysics. He tested his method for electrical detection of mineral ores in Rouyn, Québec. In 1928 he took a leave of absence from McGill to become deputy director of a government-sponsored mining expedition in Australia, where he died after a brief bout of pneumonia in 1929.

In 1848, he married Marie Anna Sophie Piedet in Paris, France. In 1853, they had a son Joseph Constantin Louis Zenon De Bielke, born in la Prairie de la Magdeleine, Quebec, who studied Chinese and worked as an interpreter at the French consulate in Shanghai.

Julius Bien was born on September 27, 1826, in Naumberg, Hesse, Germany.

He was an American lithographer. He received his education at the Kunsthochschule Kassel, and then at the Städel Institute in Frankfurt. Like many other Jews, he fought on the side of the liberals in the 1848 Revolution and fled to New York in 1849, where he established a small lithographic business in 1850. His abilities soon earned him many government contracts for engraving and printing major geographic and geological publications, including a map of the territory west of the Mississippi River, which was standard for 25 years. He produced the maps and atlases accompanying the federal census reports from 1870 to 1900, as well as atlases of New York State (1895) and Pennsylvania (1900). He won many awards and became a prominent citizen of New York as well as the first president of the National Lithographers Association (1886–1896). He was also a director of the Hebrew Technical Institute and Hebrew Orphan Asylum in New York and a president of B'nai B'rith (1854–1857, 1868–1900), contributing substantially to its internationalization. In the late 1850s, he produced a new full-size edition of John Woodhouse Audubon's The Birds of America.

He died on December 23, 1909, in New York, New York.

Born in Florence, Giancarlo Bigazzi was a music producer and composer. During the 1970s and 1980s he was one of the best-known songwriters and lyricists in Italy. Several of his songs became international hits, among them, “Gloria,” “Self Control,” “No Me Ames,” “Tu,” “Take the Heat Off Me,” and “Mama.” He also composed film soundtracks for “Mery per Sempre,” “Ragazzi Fuori,” and Gabriele Salvatore’s “Mediterraneo,” an Oscar winner. He was a member of the musical comedy group “Gli Squallor” from 1973 to 1994. The group, formed by four popular musicians for fun, was shunned by radio stations for its vulgarity but was a success, producing 14 albums. One of their films, Arapaho, was an unexpected box office hit.
