André Antonio Barbeau was born on May 27, 1931, in Montreal, Quebec.

He was a French-Canadian neurologist known for his contributions to the study of Parkinson's disease, Huntington's chorea, and Friedreich's ataxia. He received a B.A. degree from Collège Stanislas and his medical degree from the Université de Montréal and the University of Chicago. Upon his return to Montreal in 1961, he joined the neurology department of Hôtel-Dieu and established the neurology laboratory at the University of Montreal (Institut de recherches cliniques de Montréal - Montreal Clinical Research Institute), which he then led for six years. Between 1964 and 1966, his work focused mainly on oculo-pharyngeal muscular dystrophy, sometimes called “Barbeau’s disease” in Canada. Barbeau is the author of over thirty works and four hundred scientific articles. In 1980, he was made an Officer of the Order of Canada. In 1985, he was awarded the Quebec government's Prix Marie-Victorin, and in 1986, he received the Royal Society of Canada's McLaughlin Medal.

He died on March 9, 1986, in Montreal, Quebec.

Edmond Julien Barbeau was born on November 30, 1830, in Laprairie, Quebec.

He was an Assistant Receiver-General, Montreal, in the late 1800s.

In 1853, he married Aurélie Caroline Cypiot Supiot (1835–1892). He died on August 4, 1901, in Montreal, Quebec.

Marius Barbeau was best known for his ethnological and anthropological work, having published extensively in both fields while at the National Museum of Canada from 1911 to 1949. The Rhodes scholar became a specialist in French Canadian folklore and music; in his anthropological work on Pacific Coast aboriginal peoples, he focused on the peopling of the Americas, in particular promoting the theory of migration from Siberia across the Bering Strait. He was founding secretary of the Canadian Historical Association in 1922 and a founding board member of the Canadian Geographical Society in 1929. He became a Companion of the Order of Canada in 1967.

Wilhelm Nero Pilate Barbellion was the pen name of Bruce Frederick Cummings.

He was born on September 7, 1889, in Barnstaple, Devon, England.

He was an English diarist and a naturalist at heart who ended up working at the British Museum's Department of Natural History in London. He began his journal at the age of thirteen and continued to record his observations there, gradually moving from dry scientific notes to a more personal, literary style. In 1915, he was called to enlist in the British Army to fight in World War I. However, a medical officer diagnosed him with multiple sclerosis, deeming him unfit for active duty. This news profoundly affected Cummings, and as a result, his journal became much more intense and personal. His diaries were published in March 1919 under the title The Journal of a Disappointed Man. He used the pseudonym "W. N. P. Barbellion" to protect the identities of his family and friends, choosing the forenames "Wilhelm," "Nero," and "Pilate" as examples of the most wretched men ever to have lived. The book has been frequently reprinted in paperback and is considered a classic of English literature. The book is compared to the works of notable writers, including Franz Kafka and James Joyce. Barbellion summarizes his life in one of the last entries of The Journal of a Disappointed Man: "I am only twenty-eight, but I have condensed into those few years a tolerably long life: I have loved and married, and have a family; I have wept and enjoyed, struggled and overcome, and when the hour comes, I shall be content to die."

In 1915, he married Winifred Eleanor Benger Abbey (1890-1979). He died on October 22, 1919, in Buckinghamshire, England.

Thomas Barbour was born on August 19, 1884, on Martha's Vineyard, Massachusetts but grew up in Monmouth, New Jersey.

He was an American herpetologist. At the age of fifteen, he visited Harvard University and fell in love with its Museum of Comparative Zoology. He studied at Harvard University under Prof. Alexander Agassiz (B.A., 1906; M.A., 1908 and Ph.D., 1910). Barbour joined the faculty in 1911 as a Curator of Reptiles and Amphibians at the Museum of Comparative Zoology, and in 1927, he became Director of the Museum. His scientific travels took him through Africa, Asia, North America, South America, and Central America. He particularly enjoyed Panama, Costa Rica, and Cuba, which he visited on at least thirty occasions, generally staying in Soledad at the Harvard Botanical Gardens, now known as the Jardin Botanico de Cienfuegos. Barbour served as custodian of these gardens from 1927 until he died in 1946. He was elected a Fellow of the American Academy of Arts and Sciences in 1916. In 1923 and 1924, he was one of the scientists and financial benefactors who founded the Barro Colorado Island Laboratory in Panama, the location of the Smithsonian Tropical Research Institute. In 1931, Barbour organized The Harvard Australian Expedition (1931–1932). In 1934 and 1935, accompanied by his wife and his two youngest daughters, he made two journeys to Africa. He was elected to the United States National Academy of Sciences in 1933 and the American Philosophical Society in 1937. Along with more than 400 scholarly articles, Barbour wrote several books, including the autobiographical “Naturalist at Large” (1943), “Naturalist in Cuba” (1945), “A Naturalist's Scrapbook” (1946), and “That Vanishing Eden” (1944), which explores the natural world of a remote, undeveloped Florida. He is commemorated in the scientific names of many species and subspecies of reptiles, including Amphisbaena barbouri, an amphisbaenian, Anolis barbouri, a lizard, Aristelliger barbouri, a gecko, and Atheris barbouri, a venomous snake.

In 1906, he married Rosamond Pierce (1886–1953). He died on January 8, 1946, Boston, Massachusetts.
