A teacher for fifteen years, he was a graduate of KSTC in the days when it was “The Normal,” and spent forty five years on its faculty, achieving a longer continues record than any other teacher. And it was to his Alma Mater that he presented his collection of 461 specimens of woods, in addition to plants, bird’s eggs and Indian relics. He was also the one who named the trees at the Kutztown Park.

For three years he taught in Marion Township; for two years in West Leesport; and for one year in a rural school in North Heidelburg Township, in addition to the 45 years at the local institution, where he was dean of instruction from 1925 to his retirement in 1934. He began his service at the Normal as teacher of Mathematics, teaching Arithmetic, Algebra and Civil Government, also occasional Geometry, Trigonometry, not to mention Educational Sociology.
