Roger Boscovich, born in what is now Dubrovnik, Croatia, was an astronomer, mathematician, physicist, geometer, and philosopher, a Fellow of the British Royal Society, and a priest of the Society of Jesus. He studied and worked mostly at the Roman College. After the Suppression of the Jesuits, he was invited by King Louis XV of France to become Director of Optics for the Marine, an office established for him personally. Toward the end of his life he returned to Italy to publish five volumes of his yet unpublished works.
Boscovich was the first to work out a scientific approach to an atomic theory. Widely recognized in his day, he received numerous honors and was elected to prestigious societies. He specialized in solar eclipses and designed the Brera Observatory in Italy — both elements included in one of his stamps. It was his personal credibility that moved Pope Benedict XIV to remove Copernicus from the Index of Forbidden Books. More

Once in every sheet of the above stamps (position 73) the engraver, Karl Seizinger,
put an "S" as his secret mark on the palm of Boscovich's right hand.

CROATIA, 2006, the 150th anniversary of Nikola Tesla presents us with an odd connection to Boscovich, Scott 626
The stamp is based on George Grantham Bain’s 1901 photo entitled:
Nikola Tesla, with Rudjer Boscovich's book Theoria Philosophiae Naturalis,
in front of the spiral coil of his high-frequency transformer at East Houston Street, New York. More

While not a philatelic matter, the twelve bank notes of Republic of Croatia from 1991 to 1993 carried Boscovich's image. (Standard Catalog of World Paper Money, Pick #16 - 27a)
