Alfred Goldsworthy Bailey was born on March 18, 1905, in Quebec City, Quebec.
 
He was an ethnohistorian, anthropologist, university builder and administrator, and among the first of Canada's "modernist" poets. Born into a family of professors at the University of New Brunswick, Bailey was naturally interested in science, geology, history, anthropology, and literature. He graduated from the University of New Brunswick (B.A., 1927) and the University of Toronto (M.A., 1929; Ph.D. in ethnohistory and aboriginal culture, 1934), where he was introduced to the poetry of T.S. Eliot. After graduating, Bailey worked as a reporter for the Toronto Mail and Empire. In 1934, he spent a year on a Royal Society of Canada fellowship studying at the London School of Economics, where he was introduced to "leftist politics" and the poetry of Dylan Thomas. From 1935 to 1938, he worked as assistant director and associate curator at the New Brunswick Museum in Saint John, New Brunswick. The President of the University of New Brunswick (UNB) Jones offered to elect Bailey to head a history department if he could talk the province into granting the university sufficient funding. Dr. Bailey did so and held that position until 1969, during which time he not only oversaw the starting of the departments of anthropology, sociology, psychology, political science, and economics, but also laid the foundation of the provincial archives, and, as Honorary Librarian and Chief Executive Officer of the UNB Library (1946-59), was instrumental in directing and advising Lord Beaverbrook in the selection and purchase of approximately 50,000 books. In addition, he oversaw the construction, design, and funding for the new UNB library, and he served as Dean of Arts (1946-64) and Vice-President Academic (1965-69). Dr. Bailey was made a Fellow of the Royal Society of Canada in 1951, received three honorary doctorates, was made the New Brunswick representative on the Historic Sites and Monuments Board of Canada, and served on the first advisory board of the National Library of Canada, and the Governor General’s Literary Awards committee. He was appointed Officer of the Order of Canada in 1978 and received honorary membership in the Association of Canadian Archivists in 1989. UNB awarded him the title emeritus, and the City of Fredericton made him a freeman in 1984.

He wrote poetry from college through retirement. His books of poetry include Songs of the Saguenay (1927), Tao (1930), Border River (1952), Thanks for a Drowned Island (1973), and Miramichi Lightning: The Collected Poems of Alfred G. Bailey (1981).
 
 
In 1934, he married Jean Craig Hamilton (1906-1998). He died on April 21, 1997, in Fredericton, New Brunswick.

Gilbert Stephen Bailey was born on October 17, 1822, in Dalton, Lackawanna County, Pennsylvania.

He was a Baptist preacher and author. He was educated at Oberlin College and after studying theology, became a Baptist clergyman holding pastorates in various places in New York and Illinois until 1863, when he was made superintendent of the Baptist missions in Illinois, and from 1867 to 1875 he was secretary of the Baptist Theological Union in Chicago. Then he resumed preaching in Pennsylvania, Michigan, and Iowa. He also served as secretary of the Italian Bible and Sunday School Mission from 1880 to 1881 and as a missionary in Southern California from 1885 to 1886. Besides numerous tracts and uncollected poems, he published a "History of the Illinois River Baptist Association" (1857); " Caverns of Kentucky" (1863); "Manual of Baptism" (1863); "The Trials and Victories of Religious Liberty in America" (1876); "Three Discourses on the History, Wonders, and Excellence of the Bible" (1882) and "The Word and Works of God" (1883).

He died on September 28, 1891, in Pomona, Los Angeles, California.

Geologist and botanist L.W. Bailey studied under renowned scientist Louis Agassiz and botanist Asa Gray at Harvard University, from which he graduated with a B.A. in 1855. He then headed to Brown University for studies with chemist Josiah Parsons Cooke and received his M.A. there in 1859. He followed up these studies with mineralogical surveys for the governor of New Brunswick in 1863-1865, conducted with colleague George Frederic Matthews. This led to an ugly dispute with a more senior geologist, Henry Youle Hind, who appears to have felt that the two young men were encroaching on his field of expertise.
After Confederation the director of the Geological Survey of Canada, Sir William Edmond Logan, met with Bailey and Matthew in 1865 to discuss a survey of New Brunswick. The reports which the two submitted from 1872 to 1906 involved much difficult field work in which Bailey participated despite a lame leg, the result of a childhood accident. His son, Alfred, who later became an important poet and academic, often accompanied him on this field work. During this time he was also a professor at the University of New Brunswick, a position he occupied for 46 years, publishing over 100 scientific works. He received an honorary Ph.D. from the university in 1873 and an honorary LL.D. from Dalhousie University. Another honor was having a mountain named for him by his friend William Francis Ganong. When the Royal Society of Canada was founded in 1882, Bailey was a charter member.
He retired in 1907 but continued to do biological research, especially on diatoms.

Orville Taylor Bailey was born on May 28, 1909, on a farm in Jewett, New York.
 
He was an American neuropathologist and educator. He entered Syracuse University at age 15 and graduated in 1928. He completed his medical studies at Albany Medical College (Union University) in 1932 and started training in pathology at the Peter Bent Brigham and Boston Children’s Hospitals in 1933. Bailey was appointed as an instructor in pathology at the Harvard Medical School and was elected a Junior Fellow in the elite Society of Fellows of Harvard University. In 1951, he left Boston and joined the University of Indiana as a Professor of Neuropathology, where he founded a Neuropathology Section and served for eight years. He then moved to Illinois Neuropsychiatric Institute in 1959 as a Professor in Neurology, Neurosurgery, and Neuropathology until he retired in 1977. Dr. Bailey was an active member of the American Association of Neuropathologists for 57 years, served as its president, and received its Distinguished Service Award in 1983. He also served on the editorial board of the Journal of Neuropathology and Experimental Neurology and the American Journal of Pathology.
 
He died unmarried on September 21, 1998, in Chicago, Illinois.
