(translated from German by myself)

Mr. Martin F. Krafft, born on 14 February 1979, currently living at
Waldpromenade 36a in 82131 Gauting/München, Germany, joined our lab as intern
and staff member between 16 August 1999 and 17 December 1999.

Mr. Krafft took part in projects and experiments within our institute. His
ambition and his knowledge of artificial intelligence, neural networks, and
robotics made him a dependable and resourceful worker.

He assisted lectures and lab sessions by answering students' questions
objectively and intelligibly, and by helping them putting theoretical
experiments to work in the real world. Of special remark were his didactic
abilites, his friendliness, and his patience.

Within the institute, Mr. Krafft followed the research of others with
interest, and contributed scientific talks to the community. He was a pleasant
and open-minded partner in discussions, and never had a problem articulating
his position in a comprehensible fashion.

Towards his colleagues, he was always polite and suave. His humour and his
natural character were well received.

We thank Mr. Krafft for his commitment in our institute, and would welcome him
back at any point in time.
