Heinrich Schmid (6 April 1921 – 23 February 1999) was a Swiss linguist and "father" of the Rhaeto-Romance Dachsprachen ("umbrella languages") Rumantsch Grischun and Ladin Dolomitan.
After a stay in Florence he returned to Switzerland where it was very difficult for him to find a suitable occupation due to his hearing impairment.
He was eventually taken on as an employee for the Rhätisches Namenbuch (Rhaetian Lexicon of Names) and contributed for 15 years to the Dicziunari Rumantsch Grischun.
As a result, the Romansh language has been publicly recognised to a much greater extent in Switzerland and a new vitality entered the Romansh-speaking area which also included Ladin.
Schmid accepted this challenge and produced the publication entitled Wegleitung für den Aufbau einer gemeinsamen Schriftsprache der Dolomitenladiner (Guidelines for the Development of a Common Written Language for the Dolomite Ladins).
