Letters to the Honourable John H. Dunn, 1837-1838

The recipient of the letters is John Henry Dunn who was born on St. Helena (a British territory island of volcanic origin located in the South Atlantic Ocean) in 1792 to John Charles Dunn and Elizabeth Bazette. He was married to Charlotte Roberts on May 4th, 1820 and they had 6 sons and 2 daughters. He came to Canada in 1820 in which year he became the Receiver General for Canada. He held this position until 1841.Charlotte died in 1835. In 1822 he was named to the Province’s Legislative Council. He was president of the Welland Canal Company from 1825-1833. In 1836 he was named to the executive council of Upper Canada but resigned 3 weeks later with fellow counselors when lieutenant governor Sir Francis Bond refused the advice of the council. Dunn was made the Receiver General for the newly formed Province of Canada in 1841, and was elected to represent Toronto in the legislative assembly that year. He married his second wife on March 9th, 1842. Her name was Sophie-Louise Juchereau Duchsnay. They had a son and a daughter. In 1843 he resigned, and was not re-elected in 1844. He returned to England with his family and died in London on April 21, 1854. Dunn was a supporter of the Welland Canal, St. Lawrence Canals and other public improvements. Between the passage of the Canada Trade Act and the Act of the Union he had tried to insure that projects received funding despite financial constraints. He claimed that he has saved Upper Canada from bankruptcy. His son, Alexander Roberts Dunn received the Victoria Cross for his role in the Charge of the Light Brigade at Balaclava. Dunn Street in Niagara Falls is named after John Henry Dunn. The town and township of Dunnville were also named for him.

The cloud chamber and CTR Wilson’s legacy to atmospheric science

2011 is the centenary year of the short paper (Wilson,1911) first describing the cloud chamber, the device for visualising high-energy charged particles which earned the Scottish physicist Charles Thomas Rees (‘CTR’) Wilson the 1927 Nobel Prize for physics. His many achievements in atmospheric science, some of which have current relevance, are briefly reviewed here. CTR Wilson’s lifetime of scientific research work was principally in atmospheric electricity at the Cavendish Laboratory, Cambridge; he was Reader in Electrical Meteorology from 1918 and Jacksonian Professor from 1925 to 1935. However, he is immortalised in physics for his invention of the cloud chamber, because of its great significance as an early visualisation tool for particles such as cosmic rays1 (Galison, 1997). Sir Lawrence Bragg summarised its importance:

Collection of Harvard College admission form letter and bills sent to Charles Walker and his son Charles Walker, Jr., 1785-1816

This collection consists primarily of quarter bills and butler's bills from Charles Walker and Charles Walker, Jr.'s years as students at Harvard College, from 1785 to 1789 and from 1815-1816. It includes the following materials from Charles Walker: a form of admission (a printed form letter with manuscript annotations and signatures) from August 1785, quarter bills and butler's bills from 1785 to 1789, and occasional receipts of payment. The documents from Charles Walker, Jr. are less numerous, consisting solely of quarter bills from 1815 and 1816. The bills for father and son include annotations explaining the basis of additional or unusual charges, including fines for absence from lectures and prayers. The form used for the son's quarter bills, issued in 1815 and 1816, separate the amounts owed into the following categories: Steward and Commons, Sizings, Study and Cellar Rent, Instruction, Librarian, Natural History, Episcopal Church, Books, Catalogue and Commencement Dinner, Repairs, Sweepers, Assessments for delinquency in payment of Quarter Bills, Wood, and Fines. All of the bills are printed forms which were then filled out by hand, by either the steward or the butler, and issued to the students. Caleb Gannett was the College steward during both father and son's era. Joshua Paine, William Harris, and Thomas Adams served, successively, as butler during the father's era. Some of the butler's bills are signed by Roger Vose, a student who appears to have been employed by the butler in 1786 and 1787.
