In 1871 he began to lecture at the École Normale and in 1876 became professor of mineralogy at the Sorbonne, but on the death of Wurtz in 1884 he exchanged that position for the chair of organic chemistry. He collaborated in efforts to form diamonds artificially, studied the pyroelectric properties of crystals, determined crystallographic constants, and did research on ketone and aldehyde compounds. |
