He had a remarkable ability to put elegant sentences together and at the same time manage to make the most mundane topic seem fascinating. He interlaced his lectures with asides and humorous stories that not only kept one in rapt attention, but made it so the biology was hard not to absorb. As a young, eager freshman I had never experienced anything like this, and I was overwhelmed. My first university course in biology not only influenced my future as a teacher but caused me to fall in love with the algae and the fungi, and I decided right away that I wanted to 44 BECOMING A BIOLOGIST become a “cryptogamic botanist,” as anyone working with these lower plants was called at that time.

Even the way science was done did not change much; those changes came later. All the equipment in the laboratory was of the utmost simplicity: crude balances, handcranked centrifuges, lovely brass microscopes (with fantastic 16 THE WORLD OF MY ELDERS optics developed by the early German optical companies), and the simplest kind of glassware. What innovations there were involved perfecting what already existed. To give an example, Hans Spemann was able to perform his delicate experiments on amphibian embryos by inventing simple ways to make glass microneedles for his operations.

Guyénot, who was pursuing some experiments with T. H. Morgan’s fruit flies. I saw not only the normal, red-eye flies in a vial with the larvae crawling through a banana mash at the bottom, but also a white-eye mutant, which—I only appreciated many years later—was the first mutant discovered in Morgan’s fly room at Columbia University. I think my only thought at the time was how much fun it must be to raise flies and do experiments; I certainly did not have a clue as to the accomplishments of Morgan and Mendel.
