Perrin was born on July 20, 1910. He died on May 15, 1986. He worked at Falconbridge Nickel and enlisted in the RCAF on July 6, 1940 at Cornwall, Ontario.He was posted to #1 Manning Depot in Toronto; #11 EFTS Cap-de-la-Madeleine, Que; #1 SFTS Camp Borden. He received his Pilot Wing at Camp Borden on May 16, 1941. He was posted to the UK in June of 1941.

After the usual training program he was posted to #51 Squadron at Dishforth, Yorkshire.
While flying as 2nd pilot on a Whitley bomber over Calais (3rd. operation) on the night of October 24, 1941, he was wounded in the leg and back by a burst of flak which struck the aircraft right through the bomb load.
Although the bomb load did not explode, the wireless air-gunner was killed, the port engine shot away, the aillerons were damaged and the plane set on fire. The remainder of the crew bailed out safely at about 7:30 o’clock in the evening and landed in nearby fields. After landing, Perrin buried his chute and attempted to crawl to safety. A French peasant offered assistance but was too poor to be of any material aid. The next day he gave himself up, as he was in no condition to travel. The Germans placed him in a hospital in Calais, where he was X-rayed and operated on without the benefit of anaesthetic. Perrin considered the doctor did a marvelous job under the circumstance, and the wounds healed clean as a whistle. He was transferred to a hospital at St.Omer, then transferred to a hospital at Frankfurt - on - Main. On December 7th 1941, he left for Stalag 7A, 30 miles north on Munich. He was also at Stalag Luft 1, Barth and Stalag Luft 6, Hydekrug.

On his return to Canada he spent a year in Christie Street Hospital.
He was employed by the Ontario Automobile Association for over 40 years.
His first wife Florence died and in 1959 married Ombra Hull. There were three daughters Heather, Susan and Annabelle. There are now 3 grandchildren and Ombra is doing well.  Percy has 11 Grandchildren and 8 great grandchildren      June 08, 2001.
