(346666) Knorozov Main-belt Asteroid
Discovered on 21 December 2008 by Mt. Lemmon Survey at Mount Lemmon.
Yuri Valentinovich Knorozov (1922–1999) was a Russian linguist who played a key role in deciphering the Maya script. His 1952 paper, “Ancient Writing of Central America”, showed that the script was partly syllabic. The Mexican government awarded him the Order of the Aztec Eagle in 1994 in recognition of his work.Naming citation (WGSBN Bull. 5, #28, 14), IAU / Minor Planet Center, via NASA/JPL
