Bernd T. Matthias: a few stories of my academic grandfather
Bernd T. Matthias was my academic grandfather as he was thesis advisor my thesis advisor, Robert N Shelton. I was in the same room as Matthias only a few times and never had so much as a conversation with him. Even so he had a strong influence on me, and I'm grateful for that. I thought I would put down some of the stories I remember about him. He was a remarkable scientist with encyclopedic knowledge of the properties of materials and uncanny scientific instincts, which I hope to illustrate here.

My first indirect encounter with Matthias
I joined Shelton's solid state physics group in Ames, IA in 1978 to study superconductivity and magnetism. Bob (I always called him Bob and he never corrected me though everyone else called him Robert) had just arrived in Ames and was building a lab from empty rooms with concrete floors. I felt I needed a lot of hands on experience and saw the required building of equipment as an opportunity.
About the first real project Bob put me on involved the family of ternary Rare Earth Rhodium Borides typified by YRh4B4. Before Matthias physicists had studied superconductivity in nearly every element, and nearly every binary compound consisting of any combination of two elements. The prevailing view was that compounds of three elements (called ternary compounds) would be chemically more complex but exhibit no new physics compared to the simpler materials. Matthias had shown that view was wrong, so as I was getting started the new area of ternary superconductivity was just getting going.
