Marci was born in Lanškroun, near the border between historical lands Bohemia and Moravia (presently parts of the Czechoslovakian Republic).
He studied under Athanasius Kircher, and spent most of his career as a professor of Charles University in Prague, where he served eight times as Dean of the medical school and once as Rector in 1662.
The crater Marci on the far side of the Moon is named after him. He was also the personal doctor of Emperors Ferdinand III and Leopold I, and distinguished himself in the defense of Prague against the Swedish armies in 1648. In October 1654 he was given the nobility title (falckrabě) "de Kronland" (anagram of "Landskron", German name for the city of Lanškroun).
In 1667, he was elected as a member of the Royal Society.
