10/ Gilliéron most famous project is the Atlas linguistique de la France (ALF), which was first published in 1902.
He employed a field worker, Edmont, to travel to 638 locations in France to transcribe data and produce 1,900 maps.
It was also the first atlas to layer in sociolinguistic data, such as on age i.e. “chez les jeunes” (among young people).
This work is also now online: https://lig-tdcge.imag.fr/cartodialect5/#/
11/ Inclusion of critical sociolinguistic variation such as ethnicity, gender and level of education became commonplace in atlas projects of the early 20th century, with notable works including the Linguistic Atlas of New England (LANE). This was one of the first attempts to map speech in the US 🇺🇸.
Once again, the results, along with all the annotated notes, have been digitalised here: https://linguisticatlasproject.org/LANE
