As you walk in the door at Dunblane Cathedral, this window is opposite you. It's one of the later windows in the Cathedral, dating to 1968 and made by Gordon Webster. There isn't much information about Gordon Webster. He lived from 1908 till 1987 and his father, Alf Webster, made stained glass windows too. Alf died in 1915 and Gordon's mother looked after the firm until Gordon took over in 1929. Slightly confusingly the information I have also says that Douglas Hamilton looked after the firm in those years and he trained Gordon in stained glass.
They're lovely windows but I'm not sure about the thing with the blacked out eyes. I noticed that the Abbey Studio windows in the Fairmilehead church, two blogs ago, went in for the same thing. It's a little creepy.
There are another three windows by him in the chapter house. These are a little earlier at 1959, 1963 and 1966 (probably - I couldn't see the date very well because of the lip of the stone)
