John Foelker pursued his early studies in his native place, passing through all the grades of its schools to the highest when he entered the veterinary college at Stuttgart where he made his professional studies. Seeking a wider field he emigrated from his native country in January, 1849, arriving at Allentown in the same year. His five subsequent years were spent with Dr. Heckenberger in Catasauqua, adding a knowledge of practice to his already acquired theory. He then opened his office at his present place, 119 South Seventh Street. Allentown, where he successfully pursued his calling these fifty-four years. His life since then is part of our history and his pleasant good nature has been familiar to all Allentown for more than one-half century. The skill of this veteran veterinary surgeon is known to the entire Lehigh Valley and he has rendered valuable services to the farmers and horse owners of this city and county.

Dr. Foelker is an independent voter, and served the Second Ward as school director for two terms. He was a director of the Second National Bank for many years. He and family are members of the Lutheran Church. He was married Jan 20, 1859 to Sarah Ann E. Koehler, a daughter of Samuel and Lucy (Beary) Koehler, of Hanover Township.
