Historic Photos from 1959

We recently received an email with historical photographs from 1959 :

Pls find attached 5 old photos (c. 1959-60) of MMSC surroundings. I
found them while going through my deceased father?s belongings. My
mother and father lived approx. 1 yr in Deep River, while he was
working as a nuclear engineer at the Chalk River Laboratories (as part
of a Swedish – Canadian bilateral collaboration). I hope you may find
them of interest and consider posting them in your photo gallery. My
father, Erik Sjoholm, is just beneath the MMSC sign in pic #1.
