Dr. Henry Detwiller, the eldest son, became the founder of the family in America. He came to this country in company with Count Von Dome, who was the general of the French army. They embarked at Rotterdam on the ship "John," of Baltimore, and arrived at Philadelphia, Pennsylvania, in the latter part of July, 1817. In the spring of 1814, Dr. Detwiller had entered the medical school of the University of Freiburg, Baden, where he spent three years as a student. He made the trip to America for the purpose of gathering geological and mineral specimens, sailing for the new world when twenty-one years of age. He had professional charge as a physician of the four hundred passengers om the ship. Following his arrival he spent six months in Philadelphia, making preparations for further investigations along the line of research which brought him to the United States. At the end of that time, owing to the entreaty of the Count and a number of his fellow passengers, he abandoned the purpose which brought him to America, and entered upon the active practice of his profession in Allentown, Pennsylvania. Later he removed to Hellertown, where he continued as an active representative of the profession, being the pioneer of the Hahnemann School in this country.

Alter the death of his wife he returned to Switzerland. but again came to the United States and settled in Easton, where his death occurred. He was probably the oldest practitioner in the world at that time, for he continued his active connection with his profession up to the time of his demise, which occurred when he was ninety-two years of age, he having been in practice at that time for seventy-two years.
