William Birtles was born in Alexander, Manitoba in 1930. He received his early education at Alexander School. In 1948, he completed grade 12 at St. John's College School in Winnipeg. He undertook formal training in art, beginning in 1949, at the Winnipeg School of Art. In 1952, he graduated from the Manitoba Provincial Normal School. After teaching school in Winnipeg for three years, Birtles completed a Bachelor of Fine Arts with a major in Sculpture in 1958. He obtained a Bachelor of Education from the University of Manitoba in 1970. Throughout his adult years, Birtles taught in various Manitoba communities, was active as an artist, showing his work and winning awards. He was also active in the Manitoba Society of Artists and associated provincial organizations. Birtles is retired and is a resident of Winnipeg, Manitoba.
Custodial History
All of the items in the fonds were in the possession of William Birtles until their donation to the McKee Archives in 2003.
Scope and Content
Fonds consists of photographs of Ms. Sarah Birtles, Rt. Rev W.W.H. Thomas D.D, the Thomas Smith farmhouse located northwest of Alexander, and a postcard containing a photograph of Westminster Abbey. Fonds also contains two biographical sketches written by William Birtles: one of Ms. Sarah Birtles - three pages - and one of Rt. Rev. W.W. H. Thomas D.D - six pages. Also includes the program of the Composite Lodge No. 64 G.R.M., A.F. & A.M. sixty-fifth Anniversary (Alexander, MB 1961).

Crepeele locale Radiocarbon Dates. C14 report by IsoTrace Laboratory for Crepeele site 2005 XU 8.
From 2003 to 2008 field work took place at the Crepeele locale with 75 - 1m x1m units excavated.
To help establish the cultural sequence at the locale Radiocarbon dates were obtained from the three sites in the Crepeele locale.
Radiocarbon dating
The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949.
Radiocarbon dating is used to estimate the age of organic remains from archaeological sites. Organic matter has a radioactive form of carbon (C14) that begins to decay upon death. C14 decays at a steady, known rate of a half life of 5,730 years. The technique is useful for material up to 50,000 years. Fluctuations of C14 in the atmosphere can affect results so dates are calibrated against dendrochronology. Radiocarbon dates are calibrated to calendar years.
Dates are reported in radiocarbon years or Before Present. Before Present refers to dates before 1950. The introduction of massive amounts of C14, due to atomic bomb and surface testing of atomic weapons, has widely increased the standard deviation on all dates after A.D. 1700 causing these dates to be unreliable.
Accelerated mass spectrometry can more accurately measure C14 with smaller samples and can date materials to 80,000 years.
Scope and Content
Sub sub series contains radiocarbon dates from: Crepeele, Sarah and Graham sites.
