Witco Stamp Collection

Identifier: 2003-020-001

Scope and Contents

Dating from 1910 through 1983, this collection consists of postage stamps, proofs, first day covers, commemorative envelopes and postmarked envelopes organized into seven binders. Arranged by subject, the collection includes stamps from over 90 countries, many of which include full color artwork with scientific imagery or portraits of featured scientists. Symbols of chemistry are depicted in the collection, such as molecules, the metric system and the Benzene Ring. Early Alchemy is also represented, including images of Avicenna the Alchemist, thought to be the first Alchemist. Additionally, the collection includes portraits of notable scientists, such as George Washington Carver and Louis Pasteur, as well as several Nobel Prize laureates including Marie and Pierre Curie and Albert Einstein. Also of note, several panels are dedicated to Senator Brien McMahon, an advocate for the safe use of atomic energy. Topics in related sciences are also covered, including atomic energy, education, chemical industries, energy conservation, the worldwide petroleum industry, botanical and mineral drugs. (For an inventory of all subjects included, please see Container List). The stamps and other media are organized on numbered panels with the original order of the collection maintained. The quantity of media on each panel varies and the collection includes some full sheets of stamps, which are treated as individual panels. All other media is mounted and affixed to album panels individually. Typewritten notes identifying individual stamps or subjects accompany many of the panels and it is assumed that the collection's creator, Richard M. Lawrence, provided this information.
