Dave Roberts is in charge of the chemical storeroom at DePauw University, where Max and I installed the prototype of our line of museum periodic table displays in October 2003. He's such a nice guy that when he noticed our interest in elements, he found a whole cabinet of surplus elements he felt DePauw could live without. Some of them are in my collection now, most will go into future periodic table displays we create for other universities, museums, and science centers.
