Lantern Slides for Early Cornell Engineering Instruction: Home

• Lantern slides existed before computer display projectors and 35 mm slide projectors.
• Called hyalotypes, lantern slides were invented by brothers Ernst Wilhelm and Friedrich in 1848 in Philadelphia, patented in 1850.
• Lantern slides were prominent in medicine (X-rays), astronomy, physics.
• Lantern slides could be painted with various colors to enhance them.

Over 400 Lantern slides 4” x 3.25”, 6 canisters of microfilm, 21 smaller slides with equations, lecture notes were donated to Cornell University Library in February 2022. Samples have been uploaded to Box.

•Slides were purchased to aid in teaching students industrial engineering during the 1920s,1930s. 

•Faculty mentioned include Myron A. Lee, Professor of Industrial Engineering, Cornell University and Morris Simon Viteles, Professor of Industrial Engineering, University of Pennsylvania  

•Slides include pictures of steam boilers, milling machines, people operating machinery, people working in factories, automobiles, hiring practices, and equations solving problems.
