John David Hanby

John's passion for chemistry led to his inventions in environmental pollution detection, and also in petroleum analytical spectrophotometry. He founded Hanby International, based upon these revolutionary developments, which has led to a new spectroanalysis instrument unique to the petroleum industry. His company will now be led by his grandson, Charles D. Fator.

John was preceded in death by his beloved wife, Barbara Bonnefin Hanby. He is survived by his brother, Dr. Daniel Hanby and his wife Betty; sisters, Anne Hanby Siren and Mary Hanby Glassman. Also surviving is his son, Christopher Bonnefin; daughter, Celeste Eberspacher and her husband Jeff; grandsons, Charles D.
