Rudolf Vojtěch Špillar (11 February 1878 – 22 March 1949) was a Czech painter and photographer.
After completing his primary education, he found a position as a civil servant and worked as an amateur photographer; one of the first to practice pictorialism.
In 1908, together with a professional photographer named Jan Špriňar, he wrote a Compendium of Practical Photography for Amateurs.
In 1918, he began writing The Science of Photography,[2] which included contributions by Jindra Imlauf (1881–1921) and Jaroslav Milbauer [cs].
He often stayed at Jaroslav's villa in Pec, and his death in 1917 may have prompted Rudolf to enter a special school, operated by Vratislav Nechleba [cs] at the Academy of Fine Arts, Prague, which he attended until 1923.
