From ham radio to a childrens doctor


The Heidelberg capsule: the first "radio" transmitting wireless information out of the intestine

Born in Heidelberg 1945 I grew up in this wonderful city where after the war many American citizen became our neighbours. One family had a son in my age and he became my friend. At age 11 we started building radios and had a lot of fun hearing our voice on 88 MHz (!). Later on I met in the local ham radio club Dr.Noeller who worked at the famous University Childrens Hospital of Heidelberg as a pediatrician. He combined his scientific interest with his hobby. I was excited of his work constructing not only amteur radios but also a mini transmitter later on called the "Heidelberg capsule" (s. beside, courtesy to Helmut, DJ1GQ).
Construction of the Heidelberg capsule was supported by Helmut Knigge, DJ1GQ, a ham radio pioneer and leading electronic engeneer at the DKFZ in Heidelberg. As fare as I remember modulation of the carrier was dependent from the pH of the stomach fluid which supported diagnoses of diseases in the upper intestinal tract.

I was fascinated and decided to study medicine (first in Freiburg, Germany), later on I returned toHeidelberg. During study time (1967-1971, 1972 I graduated as M.D.) I always was in contact with Dr.Noeller, and I decided to join his group. Just at this time he left to go to the US since the new head of department, Prof.Dr.Horst Bickel, was not interested in "electronic medicine". But the lab was fully equipped with all a ham dreamed from!
The successor of Dr.Noeller was a biochemist (Dr.W.Kochen) who introduced myself in biochemstry. We constructed a machine to analyze biological fluids (HPLC) and I had a training in biochemistryup to 1975, when I started my training in pediatrics.
I graduated in pediatrics in 1983 and became a senior pediatrician and professor for pediatrics. In 1992 I left the University of Heidelberg and became head of Department of Pediatrics at the Kreiskliniken Reutlingen. In March 2010 I retired but in July 2010 I started again as a general pediatrician (half time) in a small place called Gammertingen. On April 1, 2015 I started a new position at the University Childrens Hospital University of Heidelberg. https://www.klinikum.uni-heidelberg.de/Willkommen.820.0.html
Now I have more time for my hobbies: beside of a revival of ham radio with a KenwoodTS-590S, in summer time I play golf (HCP 26, sorry, I try to improve). I like old houses as shown below (350 years old!), which we remodeled in the last 10 years. I continue my scientific work in genetic metabolic dieseases with main interest in the disease"phenylketonuria" and new developments like metabolomics using high resolution nuclear magnetic resonance spectroscopy. And between I work with my wife in our two gardens, love my family with two wonderful grandchildren.

The original Heidelberg capsule. It could be swallowed and transmitted information out of the intestine (1967).
Today still in use:
