A physicist who investigated magnetism, piezoelectricity and radioactivity. He built delicate balances, electrometers and piezoelectric crystals; this work on instruments helped make weak electrical effects measurable. With Marie Curie, he investigated radioactive substances under difficult laboratory conditions. The Curie ionization-current measurement illustrates how such instrumentation can turn a small signal into a quantitative comparison.[ref]
