27 or 28. Master at the same school [as Miss McGovern, later to be renamed Barbara]. Might be classed as ancient by teenagers except that he is physically perfect, strong and courageous, a gorgeous dish. Oddly, when brains are required, he can even be brainy, in a diffident sort of way. --C. E. Webber, May 1963.
27, red-brick university type, the teacher of applied science at Sue's school. Physically perfect, a gymnast, dextrous with his hands.--format document, Donald Wilson, C. E. Webber, Sydney Newman.
Originally named Cliff, Ian Chesterton (so dubbed by Anthony Coburn, the writer of the first story) was the most skeptical of the first set of Companions, taking much longer than Barbara to accept the Doctor's incredible claims of being able to travel in space and time. However, he eventually accepted his situation and even seemed to begin to enjoy it, as with the scenes with Barbara in the Roman villa (and the jokes about the refrigerator).
