French lyricist and composer Gaston Theophile Baron was born in 1874 in Armentierès in northern France. In 1908 he wrote a one-act vaudeville piece entitled “Un constat qui finit bien.” Throughout the early decades of the 20th century he was based in Montmartre, the artists’ neighborhood in Paris, where he both composed and wrote lyrics for songs. During World War I, Marianne, as the feminine symbol of the French motherland, became popular in French art and literature, and Baron wrote a nationalist song “Marianne, Marianne” in 1919. He wrote many other patriotic songs and contributed songs for the booklet "Songs of the Republic of Montmartre.” (The “Republic of Montmartre” was a charitable and cultural organization founded by a group of artists from that neighborhood in 1921.) The Bibliothèque Nationale de France holds 94 entries linked to Baron.

Barott established the architectural firm Barott, Blackader & Webster with associates Gordon Home Blackader (1885-1916) and Daniel T. Webster (1870-1939) in 1912. From 1917 to 1935, the firm operated under the name Barott & Blackader.

Ernest Isbell Barott (1884-1966) was born in Canastota, NY, and studied architecture from 1902 to 1905 at Syracuse University. Later he apprenticed at the New York office of McKim, Mead and White. In 1912 Barott formed a partnership with Gordon Blackader and Daniel T. Webster.

Hugh C. Barr was an employee of Henry Watts and Company in Pittsburgh, Pennsylvania between 1911 and 1915. Along with Henry Watts, he was the company's primary salesman, making contact with potential buyers, accompanying them on excursions to Alberta, and gathering information about land for sale in Canada. During his time with the company, Barr moved to Alberta and settled on a farm there with his family.

Joachim Barrande was born on August 11, 1799, in Saugues, Haute Loire, France.

He was a French geologist and paleontologist. He studied engineering at the École Polytechnique and the École Nationale des Ponts et Chaussées in Paris. He worked as a tutor for the Duc de Bordeaux, who later became known as the Comte de Chambord, the grandson of Charles X. After the king's abdication in 1830, Barrande accompanied the royal exiles to England and Scotland, and later to Prague.

In Prague, he initially focused on engineering projects but soon developed an interest in fossils from the Lower Palaeozoic rocks of Bohemia. From 1840 to 1850, he studied these rocks, collected fossils, and documented approximately 3,500 species, including graptolites, brachiopods, mollusks, trilobites, and fish. Barrande supported the theory of catastrophism, as proposed by Georges Cuvier, and he rejected Charles Darwin's theory of evolution and the concept of species transmutation.

In 1852, he published the first volume of his significant work, "Système silurien du centre de la Bohême." Two additional volumes were published posthumously in 1887 and 1894. In recognition of his important research, the Geological Society of London awarded him the Wollaston Medal in 1857. He was elected to the American Philosophical Society in 1862, became a foreign member of the Royal Swedish Academy of Sciences in 1870, and was recognized as a Foreign Honorary Member of the American Academy of Arts and Sciences in 1875. Barrande bequeathed his extensive fossil collection to the National Museum in Prague. In 1884, the Barrande Rocks in Prague were named in his honour, and a large plaque bearing his name was placed at the site. In 1928, a district of Prague was named Barrandov in tribute to him.

He died on October 5, 1883, in Frohsdorf, Vienna, Austria.

Sir James William Barrett was born on February 27, 1862, in South Melbourne, Victoria, Australia.

He was an Australian ophthalmologist, academic administrator, and author. He was educated at the University of Melbourne (M.B., 1881; Ch.B., 1882) where he became the first secretary of the Medical Students' Society in 1880. In 1890, he founded the Australian Medical Journal in Melbourne. He worked for two years as a resident medical officer at the Melbourne Hospital where he became a strong advocate of antisepsis.

In 1883, he went to King’s College in London (M.R.C.S., 1884; F.R.C.S., 1887) where his professor G. F. Yeo remarked on his earnestness, quickness, assiduity, urbanity, and courtesy. Sir Barrett taught at King's College, Moorfields Ophthalmic Hospital and elsewhere, gaining his main source of income from coaching in physiology for F.R.C.S. examinations.
He visited Austria and Germany and developed a lifelong affection for German language, literature and music, together with an attachment to the scientific rationality and agnosticism of Thomas Huxley. He researched the anatomy of the mammalian eye, published seventeen papers, and decided to spend his life in London on investigative work, but in 1886, he was called back to Australia for family reasons.

He served as Vice-Chancellor of the University of Melbourne from 1931 to 1934, and then as Chancellor from 1935 to 1939. He was President of the British Medical Association from 1935 to 1936, and the inaugural president of the Victorian Town Planning and Parks Association, now the Town and Country Planning Association. He was a notable supporter of Jewish refugee migration to Australia by persons fleeing Nazism.

In 1888, he married Marian Rennick (1861–1939) and in 1940, he remarried Monica Ernestine Heinze (1889–1950). He died on April 6, 1945, in Toorak, Melbourne, Victoria, Australia.
