A surprise discovery

The last couple of days have been dull and not great for photography. We had a local walk today and came home along a road we hadn't been on before. We discovered this plaque about one of the discoverer's of insulin.

My wife has been an insulin-dependent diabetic since she was 12 and had no idea that the co-discoverer of insulin lived in her home town.  She always had believed that Banting and Best discovered insulin but it seems that a Scotsman had a much larger part in this than is commonly known.
