An extraordinary event then occurred when Heyman was 38, and feeling
that he would never get a Chair. In 1963, a Chair was created at Oxford,
and Heyman duly appointed, with the promise of great things to come. However,
within a couple of months, it became clear that the funds promised were
not available, and there had never been any intention of procuring any.
This must be one of the shortest tenured positions held - after only ten
weeks, Heyman resigned from the post, never actually having gone to Oxford,
although his appointment was duly recorded in the 'Who's Who' of that
year.
He 'returned' to Cambridge to find that his lectureship had already
been filled, but his letter of resignation was soon found and torn up,
so that a new lectureship was effectively created in order to retain this
great mind. A couple of years later, in 1971, Heyman was promoted to Reader
and then became the first ad hominum Professor in the Department of Engineering.
Heyman had always been a contender for the post of Head of Department
to succeed Professor Mair, but with characteristic modesty he states that
Shercliff was 'of a different order of brightness'. On Shercliff's death,
however, Heyman stepped in to the breach.
His stated aim as Head of Department was "to make the place run as an
efficient machine. I tried to be invisible - letting people get on with
the research they wanted to do, without filling in forms". To help achieve
this end, Jacques was responsible for promoting the key administrative
staff to officer level, and thus effectively creating what is now the
office floor. The administrative staff in turn remember his fearsome eye
for precision and detail.
