y love for all nature sciences and the achievements of enlightenment traces back to the time when I was seven years old. Indeed the first book I read, apart from school, was about chemistry. It was a wonderful and optimistic time when we all wanted to reach for the moon.

olourful and interesting were my functions in the course of time as:
• programmer • software developer • consultant • computer trainer • project director • manager • graphic artist • author of books and science CD-ROMs

n 1983 I founded my company welsch & partner in order to finance my long years at the university's campus where I studied every subject I found to be fascinating. Among my more serious interests were chemistry, biology, informatics, astronomy, geology and even stranger things like sanskrit, farsi and German poetry. After all, I finally got my diploma in biology. Not to be restricted by artificial boarders was always and still is the designation.
