The crater "Lamèch" was named after Félix Chemla-Lamèch himself and proposed by Karl Müller (1866-1942).
In 1935 the IAU (International Astronomical Union) accepted this name with number 729, it was proposed by Karl Müller (1866-1942). Current ID: 3262.
Note that the crater "Müller" was proposed by Chemla-Lamèch!

Chemla Lamèch also named some craters after notable people he knew from France.
Two particular craters were named "Baldet", after Fernand Baldet, and "Myriame", after Soeur E.-E.-Ch. Myriame.
However, in 1935 the IAU (International Astronomical Union) didn't accept these designation;
"Baldet" was designated 933 "Cassini E" and "Myriame" was designated 727 "Eudoxus A". Current ID's: 8143 and 9007 (2006).
Fernand Baldet (1885-1964) was a French astronomer.
Myriame was most likely a nun from a monastery, who did astronomical observations.
