'''Antonín Bečvář''' {{IPA2|ˈantoɲi:n ˈbɛtʃva:r̝̊}} ([[June 10]] [[1901]] – [[January 10]] [[1965]]) was a [[Czech Republic|Czech]] [[astronomer]] who was active in [[Slovakia]]. He was born (and died) in [[Stará Boleslav]]. Among his chief achievements is the foundation of the [[Skalnaté Pleso Observatory]] and the discovery of the comet [[C/1947 F2]] (Bečvář) (also known by the designations 1947 III and 1947c).
Bečvář is particularly important for his [[star chart]]s: he led the compilation of the ''Atlas Coeli Skalnate Pleso'' (1951), published by [[Sky Publishing Corporation]] as the ''Skalnate Pleso Atlas of the Heavens'', which was the state-of-the-art atlas of its kind until [[Wil Tirion]]'s "Sky Atlas 2000.0" in 1981. He also compiled ''Atlas eclipticalis, 1950.0'' (1958), ''Atlas borealis 1950.0'' (1962), and ''Atlas australis 1950.0'' (1964).
The [[asteroid]] [[4567 Bečvář]] and the [[Bečvář (crater)|Bečvář crater]] on the [[Moon]] were named in his honour. American [[Avant-garde]] composer [[John Cage]] used Bečvář's star charts as the basis of several works: ''[[Atlas Eclipticalis]]'' (1961–62), ''[[Etudes Australes]]'' (1974–75), ''[[Etudes Boreales]]'' (1978) and ''[[Freeman Etudes]]'' (1977–80, 1989–90).
