Every second of October, geotechnical engineers around the world remember Karl Terzaghi on his birthday! Terzaghi is the father of soil mechanics, and I don't think it is cliche to say he is also the father of our profession. So happy KTB 2016! I always like to celebrate by reading some of his quotes, many of which seem like they could have been written to us today…like this one: The one thing an engineer should be afraid of is the development of conditions on the job which he has not [...]

Art is unique in this industry from what I can tell in that he wasn't hired from outside to run the company, he came up from the ground floor as a staff engineer with Moretrench, the only company he has worked for in his engineering career. I love his little anecdote about how he aced three exams in an architecture class. The professor asked him if he wanted to be an [...]
