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.

Lady Evelyn Katherine Campbell was the daughter of George Douglas Campbell, 8th Duke of Argyll. She married James Baillie-Hamilton, son of Admiral William Alexander Baillie-Hamilton and Lady Harriet Hamilton.

Sir William Alexander Baillie-Hamilton, KCMG, was born on September 6, 1844, in Sussex, England, the son of Admiral William Alexander Baillie-Hamilton and Lady Harriet Hamilton.
 
He was a Scottish civil servant who graduated from Harrow in 1863. He joined the Colonial Office in 1864 and rose to the rank of First-Class Clerk in 1879. Between 1886 and 1892, he served as Private Secretary to the Chief Secretary for Ireland and the Secretary of State for the Colonies. He also served as Secretary to the Colonial Conference in 1887 and was Chief Clerk of the Colonial Office from 1896 to 1909, when he retired. He was also a qualified barrister and was admitted to the Inner Temple in 1871. In 1884, Baillie-Hamilton published a novel titled "Mr. Montenello: A Romance of the Civil Service". He was also a keen sportsman in his youth and played for the Scottish side in the first football match against England in 1870. Baillie-Hamilton received several honors during his career. He was invested as a Companion of the Order of St. Michael and St. George in 1887 and as a Companion of the Order of the Bath (C.B.) in 1892. He was promoted to Knight Commander of the Order of St. Michael and St. George (K.C.M.G.) in the 1897 Diamond Jubilee Honours. In 1901, he was appointed an Officer of Arms of the Order of St. Michael and St. George by King Edward VII. In 1911, the title was changed to Gentleman Usher of the Blue Rod, a position he held until his death.
 
In 1871, he married Mary Aynscombe Mossop (1844-1919). He died on July 6, 1920, in Middlesex, England.

Composer, singer and pianist Charly Bailly was born in Macon, France, and wrote supposedly his first song at age eight. He is known for such early songs as “Le vagabonde de rêve” (1949), Menace de Mort” (1950) and “La femme orchidée” (1952), and for his soundtrack for the 1950 crime film “Le furet” (the ferret). His career took off when he teamed up with André Varel, whom he had met in North Africa during World War II; calling themselves “Varel et Bailly” they created songs for such famous singers as Maurice Chevalier and Edith Piaf. The two became co-directors of “Les Chanteurs de Paris,” a group of 7 young graduates of the Université de Paris, and before that, members of “Les petits chanteurs de Paris.” Varel was the lyricist and Bailly the composer and pianist. In 1956/1957 they made their American debut with great success, performing for four weeks in the Empire Room of the Waldorf Astoria in New York City and making guest appearances on The Ed Sullivan Show and The Garry Moore Show. During their 1959 North American tour they were booked for 65 concerts in 13 weeks, many at college campuses. They began a schedule of American tours during the winter, French tours during the spring, and summers spent at a chateau in Chartres with other musicians, artists and friends, some from Montreal and Vancouver. During his lifetime, Bailly wrote or co-wrote over a hundred songs.

William Hellier Baily was born on July 7, 1819, in Bristol, Gloucestershire, England.

He was an English paleontologist. From 1837 to 1844 he was Assistant Curator in the Bristol Museum, a post he relinquished to join the staff of the British Geological Survey in London. In 1854, he became an assistant naturalist. In 1857, he was transferred to the Irish branch of the Geological Survey, as an acting paleontologist and senior geologist, and retained this post until the end of his life. He was responsible for the identification and curation of thousands of fossil specimens found in Ireland. He was the author of many papers on paleontological subjects, and of notes on fossils in the explanatory memoirs of the Geological Survey of Ireland. He published a useful work entitled “Figures of Characteristic British Fossils, with Descriptive Remarks” (1867–1875). He was also an accomplished artist and lithographer.

He died on August 6, 1888, in Dublin, Ireland.

Francis Bain was born on February 25, 1842, in North River, Prince Edward Island. 
 
He was a self-educated farmer, geologist, ornithologist, botanist, author, and artist. As a boy, he was fond of reading and developed a liking for natural science. After the death of his older brother in 1862, the family farm became his sole responsibility, with formal schooling curtailed, but Bain continued studies of classics, mathematics, French, and German on his own. In the 1860s, he began travelling all over the Island to pursue his interest in natural science. He considered himself foremost a geologist. He mapped the province’s bedrock and collected, illustrated, described, and identified many fossils. He also discovered a species of fossil fern on PEI that Sir William Dawson subsequently named Tylodendron baini. In 1892, he was commissioned by the federal government to investigate the feasibility of constructing a submarine tunnel from PEI to New Brunswick. Bain’s enthusiasm to share his learning led him to engage in extensive writing and lecturing. Between 1881 and 1893, he published over twenty scientific papers and two books, “The Natural History of Prince Edward Island” (1890) and “Birds of Prince Edward Island, Their Habits and Characteristics” (1891). He also published over fifty natural science articles in a half-dozen Canadian and American scientific journals. His articles included lists and records of birds, shells, plants, butterflies, fossils, and geological formations. His career as a public speaker on botany, geology, and the proposed tunnel to New Brunswick, often illustrated with his drawings, began about 1885. Bain's knowledge and understanding of natural science mark him as the first Islander to whom the contemporary term ecologist can appropriately be applied.
 
In 1875, he married Caroline Matilda Clark (1852–1913). He died on November 20, 1894, in North River, Prince Edward Island.
