Most of the collection was acquired in March and May of 1985 from Ellen (Nellie) Ellery Appel (b. 1903), a grandaughter of Theodore Appel, and combined with Theodore Appel papers already housed in the Archives and Special Collections Dept. Note that as some Appel family members have changed the spelling of their surname from an "el" ending to an "le" ending, this inventory attempts to reflect the correct spellings as used by each family member.
