The periodic table and its creator, Dmitry Mendeleyev.

Description
Until he came up with the table, Mendeleyev was known mainly for his extravagant hair (he cut it only once per year). Atomic numbers are shown above the element symbols. Some of the symbols are abbreviations for their Latin names. For instance, Pb (lead) is short for plumbum; the word “plumbing” is related—ancient Romans made their water pipes with lead. Appendix IV shows the table in more detail.
