OpenBabel and JOELib were derived from the OELib Cheminformatics library. In turn, OELib was based on ideas in the original chemistry program Babel and an unreleased object-oriented library called "OBabel."
The project logo is just the word JOELib in the Tengwar script of J. R. R. Tolkien. The letters are grouped as JO-E-Li-b.
