 So, I told you about what prompted me us to look for this position, but I found out when I arrived there that it was a remarkable time for this government metallurgy lab in Ottawa that they were in the process, or I had just hired something like seven or eight new scientists, I was one of them, all to work on pipeline steel. So, at this time, 1972, there was a big plan for an arctic gas pipeline and some wise person in this government lab decided they would build up a group of metallurgists of expertise and strength in this area, both to assist the Canadian steel companies that were manufacturing steel to make the pipe and also to support the regulatory. So it was an amazing time of all these new people starting this work, new equipment, it was ideal for a young research scientist to sort of come in and with all these facilities begin to do research on steel. So this is really where I started my research in steel and that's what I've been doing ever since then for the rest of my life.
