The Historical Dictionary of Thailand notes:
Tai linguist William J. Gedney called him "probably Thailand's most gifted man of letters of the twentieth century". James N. Mosel, discussing Thai poetry of the early and mid 20th century, notes that:
King Rama VI (Vajiravudh), himself an accomplished author and translator, formed a literary club to promote good writing in Thailand. Bidyalongkorn, a member of the club, formulated a series of rules encouraging correct and concise language, as well as strict observance of classic Thai verse structures. An innovator as well as a traditionalist, he was an influential adopter of novel meters of the chan verse type which, before 1913, had remained unchanged for centuries.
