Does anyone know who coined the term "Thumbnail" , as relates to images? And did this term predate the web?

"The word "thumbnail" is a reference to the human thumbnail (such as the one in the picture to the right) and alludes towards the small size of the image or picture, comparable to the size of the human thumbnail.[1][2] While the earliest use of the word in this sense, dates back to the seventeenth century,[3] the American Heritage Dictionary of Idioms is reported to have documented that the expression first appears in the mid-1800s to refer to 'a drawing the size of the thumbnail'.[4] The word was then used figuratively, in both noun and adjective form, to refer to anything small or concise, such as a biographical essay. The use of the word "thumbnail" in the specific context of computer images as 'a small graphical representation, as of a larger graphic, a page layout, etc.' appears to have been first used in the 1980s.[3]"

As for the name of the individual who was the first to use it... I doubt that information exists.
