He took a particular interest in explaining time and the workings of the RGO to others, which led to him serving as Public Information Officer and, after his early retirement in 1981, helping at the Observatory Science Centre.

Nathy met his wife Elizabeth (Betty) at Abinger where the Time Department had been located during the war.
