Milan Rastislav Štefánik was a Slovak politician, diplomat, aviator, Freemason, and astronomer. During World War I, he served at the same time as a general in the French Army and as Minister of War for Czechoslovakia. As one of the leading members of the Czechoslovak National Council, he contributed decisively to the cause of Czechoslovakian sovereignty, since the status of Czech- and Slovak-populated territories was one of those in question until shortly before the disintegration of the Austro-Hungarian Empire, in 1918.
His personal motto was "To Believe, To Love, To Work".
