John Dewey visited Hawai'i on three separate occasions. Of all three trips, by far the most important, as far as Dewey's influence on education in Hawai'i is concerned, was in 1899 when he came with his wife, Alice Chipman Dewey, to help launch the University Extension program in Honolulu. The Deweys' second trip was a very brief one--twenty years later, in 1919, during a brief stopover on their way to Japan and thence to China. It is possible that they made a similar stop on their return, in 1921, but there is no evidence of this in the Dewey correspondence.1 The final visit took place in 1951 when Dewey was ninety-one years old and in poor health. Indeed, Dewey's health appears to have been one of the main reasons for his visit, in which he was accompanied by his second wife, Roberta Lowitz Grant, and their two adopted children, Adrienne and John Jr. Dewey's first trip is extensively described in this article, followed by brief descriptions of his second and third trip.
