I tried to google search for an image, and there is surprisingly little about this window on the web. I had guessed Halley based on a search of London Astronomers who might have contributed money to the Church. I thought that Newton was probably too much of a curmudgeon to get a window, and probably would not be shown as an astronomer.

Since the Windows may not have survived WWII, it could be that there is no chronistic connection between the windows, and when Wren designed the church.
