A short bio on Bert Topham (1893-1962) appears on page 148 of Looking Up.

Note from Geoff Gaherty:

When I joined the Montreal Centre in 1957, they had only a few months before they purchased Bert Topham's 165mm (6.5) f/15 refractor, equatorial mount, and motor drive, and mounted it in what was to become the Isabel Williamson observatory. I had the use of that fine telescope on many occasions, until vandals broke into the dome and stole the objective.

Here's a picture of the Topham refractor in its new home in Montreal, taken sometime in mid-1957:
