Morgenthaler is a family name (or surname) from German speaking Europe.
The name Morgenthaler means person from the morning valley. It developed from the description of a person coming from a place called Morning Valley; in ancient German orthography Morgen Thal. The final syllable (or suffix) -er signifies geographical origin of a person (as in English New Yorker). The distribution of the name in Europe and around the world leads to the conclusion of most probable origins of the name in Switzerland or in southern Germany.
Mainly in Switzerland (with an amassment in two Cantons of Switzerland: Bern and Aargau) and in Germany (with an amassment along the southern Rhine valley). By immigration also in Austria, France, the United States and other countries.
