Asian Week has published the first obituary for Ron Takaki that I've found. Below is a quote from this obituary:
Ron Takaki was one of the most preeminent scholars of our nation’s diversity, and considered “the father” of multicultural studies. As an academic, historian, ethnographer and author, his work helped dispel stereotypes of Asian Americans. In his study of multicultural people’s history in America, Takaki seeked to unite Americans, today and in the future, with each other and with the rest of the world.
Paz, luz, y amor.
