Charles Lapworth was born on September 20, 1842, in Faringdon, Berkshire, England.

He was an English geologist. He was trained as a teacher at the Culham Diocesan Training College near Abingdon, Oxfordshire. His first post, in 1864, was in Galashiels, and in 1875, he was appointed to Madras College in St. Andrews. Lapworth’s interest in geology started shortly after his move to Scotland. Largely self-taught in the subject, he soon began to make significant contributions towards unravelling the geology of the Southern Uplands. His researches were published in 1899, in the "Memoir on the Geology of the Southern Uplands of Scotland". In 1881, he was appointed as the first Professor of Mineralogy and Geology at Mason College, the forerunner of the University of Birmingham. His title was subsequently changed to Professor of Physiography and Geology. He studied the rocks of the Midlands and Welsh Borderland and took groups of students, amateur, and professional geologists on field excursions. He mapped the Lower and Middle Cambrian rocks. The Lapworth Museum on the campus of the University of Birmingham, one of the oldest specialist geological museums in Britain, houses an extensive collection of fossils and minerals dating back to 1880. In 1888, he was elected a Fellow of the Royal Society and in 1891, he was awarded their Royal Medal. In 1899, he received the highest award of the Geological Society of London, the Wollaston Medal. In 1902, he was elected President of the Geological Society (1902-1904). Aberdeen University awarded him an honorary doctorate in 1884 and Glasgow University in 1912 (both L.L.D.). In 1916, he was elected an Honorary Fellow of the Royal Society of Edinburgh.

In 1869, he married Janet Sanderson (1849-1924). He died on March 13, 1920, in Kings Norton, Worcestershire, England.

Cornelius Wilson Larison was born on January 10, 1837, in Sandy Ridge, New Jersey.

He graduated from Lewisburg University, Pennsylvania, and Geneva Medical School, New York (1863). He became a professor of Natural Sciences at the University of Lewisburg (later Bucknell University), Pennsylvania. He settled in Ringoes, New Jersey, where he practised medicine his entire life. He was also an author, natural scientist, phonetic expert, historian, editor, reporter, publisher, genealogist, headmaster, and the founder of two private academies, the Ringoes Seminary and the Academy of Science and Art. As an advocate of spelling reform, Larison established the Fonic Publishing House, which produced books, magazines, and pamphlets advocating simplified phonetic spelling. Its principal products were The Jurnal of American Orthopei, published bimonthly from 1884 to 1909 and written mostly by Larison in phonetic spelling, and The Jurnal of Helth (folded after 12 issues). His long medical career is told in the book "The County Doctor," by Dr. Harry B. Weiss (1953).

In 1863, he married Mary Jane Sergeant (1836-1917). He died on April 15, 1910, and was buried in Ringoes, New Jersey.

François-Antoine LaRocque was born on August 19, 1784, in L’Assomption, Quebec, and died on May 1, 1869, in Saint-Hyacinthe, Quebec. He was the son of François-Antoine LaRocque, the first representative for the county of Leinster, and Angélique Leroux, the daughter of merchant Germain Leroux. On January 26, 1818, LaRocque married Marie-Catherine-Émilie Cotté, daughter of merchant Gabriel Cotté, in Montreal. They had one son named François-Alfred-Chartier. In 1806, LaRocque moved to Montreal to run a trading house. He was a partner of Joseph Masson and then organized his own business under the name of LaRocque, Bernard, et Compagnie in 1832. In 1855, LaRocque entered the Hôtel-Dieu of Saint-Hyacinthe, where he spent the last years of his life. During the War of 1812, LaRocque served as an ensign in the 3rd militia division of Lower Canada and as a captain in the 5th battalion of Chasseurs Canadiens. Upon his return to Montreal after the war, he was decorated with the Châteauguay medal.
