62890 Lenaerts reporting back from Cambridge, part 2 - Jan-Mar 1948

Second part of a file of photocopies of correspondence between Ernest Lenaerts and his managers at Lyons - John Simmons, W.J. Edwards and T.R. Thompson, during Lenaerts' secondment to the Cambridge University Mathematical Laboratory, working as part of the EDSAC team under Maurice Wilkes. 

Many of Lenaerts' original letters were written enclosing reports on the progress of the EDSAC team, but photocopies of the reports themselves were not included in this file of photocopies.  Presumably the original reports are included in the archive copy held at Manchester, ref. GB 133 EHL/2 EDSAC.
