The Brooks and Melba Labbe Caldwell Collection contains materials generated, collected, and assembled by Brooks Caldwell and his wife Melba Labbe. Documenting their educational histories, professional lives as a pharmacist (Brooks) and florist (Melba), and social interests, this collection includes certificates, photographs, postcards, publications, an account ledger, and a scrapbook. Brooks Caldwell graduated from Oregon Agricultural College in 1925 in Pharmacy.
These records were generated by the OSU Chapter of the Honorary Society of Phi Kappa Phi. They document the origins and development of the group, the yearly process of the selection of pledges and members, sponsorship of the Biology Colloquium lecture series, and the awarding of fellowships and scholarships by the chapter. The OSU Chapter of Phi Kappa Phi was established in 1924.
