As a fun fact a lot of the people who live there believe(d) that Nikola Tesla was a Czech/Slovak due to the (at the time) prevalent domestic 'Tesla' brand name on various electronics (including popular TVs).
Also I've never met anyone who thpught that. On the other hand there is the folk etymology of TeSla = "technicky slabsi" = "technologically inferior", which has some grain of truth as for political reasons the Tesla conglomerate tried to disassociate itself from Nikola Tesla by explaining the name as abbreviation of either "technika slaboprouda" (phrase that essentially means "electronics", litetally "low voltage technology") or "telefon slaboproud" (~ phone and electronics).
