CANTON -- The St. Lawrence County Historical Association, 3 E. Main St., will host a talk about the history of early 3D images. Erwin Selleck will speak about Stereo Views of St. Lawrence County Thursday, Oct. 18 at noon as part of the Brown Bag Lunch series. Bring a lunch, but dessert and beverages will be provided.

In stereo viewing, two images of the same subject are taken from slightly different perspectives and viewed in a device that allows the image to appear in 3 dimensions. Stereo viewing became very popular in England after Queen Victoria enjoyed it at the Crystal Palace Exposition in 1851, and the use of stereo views spread around the globe.

The speaker for Stereo Views of St. Lawrence County is Erwin Selleck, a retired physical science professor from SUNY Canton, who authored “Technical Physics,” a textbook on mechanical physics. He will showcase some of his personal collection of stereo views of St. Lawrence County at the Brown Bag Lunch. Selleck will also display stereo views from the archives of the St. Lawrence County Historical Association, where he is a volunteer. Selleck was born in Potsdam and was a professor at SUNY Canton from 1967-2007. Erwin and his wife Becky are antique dealers and operate Breakable Collectibles, Heuvelton.
