L. Simoni started working as an optics and reflector designer and lighting research and development consultant to luminaire manufacturers, with a background in engineering. He began holding refresher courses, usually for technical departments of manufacturers, and suddenly found himself teaching lighting design to interior designers. When the shock subsided, he was captivated by the challenge of teaching a technical course to students with a non-technical background. L. Simoni lives in Milan, Italy, in a house which, until recently, contained more computers than doors.
