E. A. Colquhoun was the ‘Centennial President.’ Emerging from the shadow of the telescope-building era, he took the helm in 1967 with a different focus: professionalization. While the club’s engineers finished the optics, Colquhoun finished the paperwork, securing the Letters Patent that incorporated the Hamilton Centre in 1968. He transformed a hobby club into a legal institution, ensuring it could own the land and observatories that future generations would build.”
E. A. (Edward) Colquhoun served as President of the Hamilton Centre during one of its most transformative years: the Centennial Year (1967–1968).
While J. Gordon Craig is remembered for the “Hardware” (the 10-inch telescope), Colquhoun should be remembered for the “Software” (the legal incorporation and the Centennial celebrations). He was the steady hand that transitioned the club from a local group of amateurs into a legally recognized, modern corporation.
Here is the breakdown of his presidency, his work, and the “Craig Overlap.”
1. The Man: Who was E. A. Colquhoun?
• Name: Edward A. Colquhoun.
• The Family Connection: In Hamilton, the name “Colquhoun” is royalty. He is almost certainly a descendant of Edward Alexander Colquhoun (1844–1904), a former Mayor of Hamilton (1897–1898) and Member of Parliament.
• Profession: Unlike the engineers (like Craig) or the academics (like the McMaster profs), Colquhoun appears to have had a background suited to administration and governance. This aligns with his primary legacy: legal incorporation.
2. The Presidency (1967–1968): The “Centennial” Shift
Colquhoun took the chair at a moment of peak activity. His term wasn’t about “business as usual”; it was about managing two massive projects that came to fruition simultaneously.
A. The “Craig Overlap” (The Handover)
You asked about the overlap with J. Gordon Craig. Here is how it worked:
• 1966–67 (Craig’s Term): This was the “Construction Phase.” Craig spent his term physically building the Centennial Telescope (the 10-inch f/8 reflector). His presidency ended with the casting of the massive aluminum mount at his farm in Lynden, Ontario, in July 1967.
• 1967–68 (Colquhoun’s Term): This was the “Operational Phase.” Colquhoun took over just as the telescope was finished. His job was to inaugurate it, organize the public “Centennial Field Nights,” and manage the influx of new members that the Apollo program and the Centennial hype brought in.
B. The Crown Jewel: Incorporation (1968)
If Craig built the telescope, Colquhoun built the Corporation.
• The Achievement: Under Colquhoun’s leadership, the Hamilton Centre successfully applied for legal status.
• The Result: On September 13, 1968, the club was officially Letters Patent incorporated as “The Royal Astronomical Society of Canada 1968, Hamilton Centre.”
• Why it mattered: This allowed the club to own property (like the Observatory land), hold insurance, and operate as a legal entity rather than just a club. This was Colquhoun’s specific, lasting contribution to the club’s longevity.
3. Writings & National Work
Colquhoun was active in documenting the history of the centre, realizing that 1967 was a time to look backward as well as forward.
• “Sixty Years in Orbit” (1969): He was a key figure in the production of the special “Centennial” issue of Orbit (the newsletter), which was released just after his term in Jan 1969. This document is the primary source for much of the club’s early history (1908–1968).
• The “lost” Calgary Connection: Interestingly, RASC records show an “E.A. Colquhoun” speaking at the Calgary Centre in January 1971 alongside fellow Hamilton heavyweight Peter Ashenhurst. This suggests Colquhoun remained active nationally and may have traveled to other centres to share Hamilton’s success story (or perhaps moved there later).
