Johannes Vilhelm (John William) Lystrup was born in Copenhagen, Denmark in 1879. He emigrated to the United States in June 1905 and began working for Edison soon afterwards.

Some of the documents in the collection were too fragile to scan; excerpts can be found in the online inventory (items 6, 9-11, 17).
John W. Lystrup was a chemical engineer who spent many years working in Edison's laboratory for his Edison Storage Battery Co. He retained the notes Edison sent him containing detailed instructions about the experiments to perfect the battery; some of them have Lystrup's notations at the bottom showing what he did in response. Most of them were written 1906-ca. 1910. Lystrup later placed the notes in a scrapbook along with some printed images, pictures, and letters. The group was acquired from Lystrup's great-grandson.
