11437 Cardalda           Discovered 1971 Sept. 16 by J. Gibson and C. U. Cesco at the El Leoncito Station.
Carlos Cardalda (1883-1961) was an enthusiastic amateur astronomer who cofounded the Argentinian Association of Amateur Astronomers in Jan. 1929, since which time it has amassed over ten thousand members. Cardalda was also instrumental in founding a similar association in Uruguay in 1952.
