Patents by Descendants of Casper Glattfelder

The program for the 2020 Glattfelder Reunion was to be titled, "The Glattfelders and Their Patents." Harry Gladfelter approached the Association with the idea in 2019, and due to all the complications of the pandemic it was decided to postpone the presentation until 2021.

Harry, a holder of 16 patents himself, was doing some research and happened upon numerous Glattfelder descendants with patents, some of quite significance. Harry's list continued to grow, leading to the decision to pare down the 2021 program, with the expectation of more on the subject in years to come. Deciding to pare down the program led to the desire to share the list of patents that was compiled so that we could acknowledge other patent holders that are not included in the presentation(s). 

Among those on Harry's list is John Glatfelter, who has 30 patents with more pending. John took it upon himself to compile the following list, which is likely to continue growing as he, Harry, and others uncover more amazing Glattfelders and Their Patents.
