Excerpt from Phytologia, Vol. 89: An International Journal to Expedite Plant Systematic, Phytogeographical and Ecological Publication; August, 2007 Dr. Wagner was the lab instructor in Botany 101; Dr. Jones was the lecturer. Lab was more interesting, there were microscopes to use, Chlamydomonas to see, and gametophytes to confound with sporophytes. Dr. Wagner was a man in motion, with a strong but not a tall build, leaning forward, like a linebacker, and rejoicing in the scrum of knowledge. What thrilled me was that at the end of the term he asked me if I would like to be his lab assistant the next autumn. And get paid! I discovered I knew the style of Dr. Wagner before I met him, having had Dr. Edgar T. Wherry (1885-1982) as my teacher at the Barnes Foundation Horticultural School, in Merion, pa. 1 was a freshman in high school when I attended his classes. Wherry made no concession to age; he merely assumed everyone who attended a lecture was eager to hear what he had to say, just as later, under the tutelage of Dr. Wagner, I learned that his commanding enthusiasm for his subject and life left no room for indifference among any member of his audience.
