Louis Daguerre, born 18 November 1787, died 10 July 1851, is one of the fathers of photography. A street in Paris is named after him. A plaque in Paris shows where he invented and refined the daguerreotype, the first publicly announced photographic process, and the first to come into widespread use during the early 1840s.

Ruder Josip Boškovic (18 May 1711 – 13 February 1787) was a physicist, astronomer, mathematician, philosopher, diplomat, poet, theologian, Jesuit, and a polymath from the city of Dubrovnik in the Republic of Ragusa (today Croatia), who studied and lived in Italy and France where he also published many of his works.

He is famous for his atomic theory and made many important contributions to astronomy, including the first geometric procedure for determining the equator of a rotating planet from three observations of a surface feature and for computing the orbit of a planet from three observations of its position. In 1753 he also discovered the absence of atmosphere on the Moon.
