Very little has been written about Pierre I de Grandson (d.1258), and yet he was one of the most important members of the Vaudois nobility during the first half of the 13th century as the counts of Savoy began their dominance of the Pays de Vaud. From widely scattered data the author presents in this two-part article a study of Pierre and his immediate descendants, whose brilliant careers, wealth and prestige both in Vaud and in England were enabled by a policy of realistic and interested co-operation with the house of Savoy developed by Pierre and his brother Henri de Champvent, and continued by Pierre's famous son Othon I de Grandson. Evidence from English and Swiss sources shows that Pierre fathered at least six sons and probably some nine daughters, most of whom can be identified as Othon's sisters.

Part 1 of this two part article examines the lives of Pierre de Grandson and his wife Agnès de Neuchâtel; and biographical data is provided for their sons Othon, Girard, Jacques, Henri, Pierre and Guillaume (William).
