Edward Hart (1854-1931) was a chemist with a PhD from Johns Hopkins University (his was among the first Hopkins doctorates ) who taught at Lafayette College, in Easton, Pa., for some 57 years. He patented a bottle for storing acids in 1890 and received the John Scott Medal for this achievement in 1891. This bottle, which is of that sort, is made of ceresin, a naturally-occurring waxy substance akin to paraffin. The inscription on the outside reads “Acid Hydrofluosilicic.”
