I started at NRC in 1956 as a student I was working for W.E.K.Middleton,
Ron Bedford and Roy. In September I decided to stay on at NRC and I
remained there for 38 years. In the picture next to the
spectrophotometer there is a rack with counters and a magnetic tape
reader. Roy had installed magnetic pickups on the spectrophotometer to
read the reflectance and transmittance of samples. The signals would
then go to the counters and to the magnetic tape. This made the reading
and calculations of the transmittance and reflectance much easier. When
I first started on the spectrophotometer I had to read all the values
off the graph paper at every 10 nm from 380 to 760 nm then apply the
calculations to obtain the tristimulus values and chromaticity
coordinate values which took many hours and lots of patience.
