After 1948 he designed for various places e.g. Wedgewood, but was primarily a professor at the RCA, and then involved with the Festival of Britain and some prestigious commissions - such as a kettle for the Duke of Edinburgh (it was a Xmas pressie for the Queen apparently!) I've read all the obits I can find online (around 6 of them) and they all include slightly varied detail but they all refer to the glass designs as either during the time Goodden had his own design practice (1933-39) or before 1948.
