Barbara Neumann
Barbara Zsusanna Neumann (; 30 November 1914 – 25 November 2002) was a Hungarian mineralogist and clay scientist who invented the chemical synthesis, synthetic clay laponite. In 2022, the Mineralogical Society of Great Britain and Ireland named their senior medal in her honour. Biography Neumann () was born in Szolnok, Hungary on 30 November 1914, to Jewish parents. She moved to Budapest, and completed a degree in physics, and doctorate in X-ray diffraction. In 1939, she married Gyorgy Emődi. Emődi was conscripted into the army and died of typhus early in World War II. During her PhD, Neumann studied the mineralogical structures of clays using X-ray diffraction. One of the samples she worked on was a natural clay called Fuller's earth, provided by the Fuller's Earth Union. In 1939, Neumann wrote to the FEU suggesting that she could help to improve their product. Following an interview, Neumann secured a job with the company, and moved to Redhill, Surrey.

The town was first officially mentioned under the name Zounok in 1075. In the following centuries, it was recorded variously as Zounok, Saunic, Zounuc, and Zawnuch. The variety of spellings likely comes from phonetic discrepancies occurring when Hungarian sounds were recorded using the Latin alphabet.
