Jean-Dominique Cassini (1625-1712), a French astronomer, born at the Paris Observatory and later its director, son of César-François Cassini de Thury and grandson of Giovanni Domenico Cassini. He worked extensively on Longitude, publishing an account of testing Pierre Le Roy’s chronometer in 1770, and completed his father's monumental map of France, published 1793. However his career came to an end during the French Revolution. Facing opposition from the National Assembly, he resigned, was briefly imprisoned, then spent the last fifty years of his life in retirement. He died aged 97. The portrait was published in 'Allgemeine Geographische Ephemeriden' (Universal Geographical Ephemerides (i.e. encyclopedia)) by Friedrich Bertuch et al.
