After retiring from missionary work in 1961, he was preoccupied with placing the finishing touches on his masterpiece, The Modern Reader's Japanese-English Character Dictionary,[2] which first appeared in print the following year. The work, which was posthumously revised and expanded by a team led by John H. Haig at the University of Hawaii at Manoa, was reissued in 1997 as The New Nelson Japanese-English Character Dictionary;[3] however, many scholars, teachers, and students continue to use the original edition of Nelson's dictionary, which has remained in print, because of changes made in Haig's edition that are viewed as impairing the functionality of the work. It is one of the most authoritative Kanji dictionaries for English learners of the language, and displays particular sensitivity to the difficulties they may have with the Kangxi radical system traditionally used to classify Kanji.
While President of Philippine Union College, Nelson also served as a chaplain at the New Bilibid Prison. On January 19, 1951, he provided pastoral support for the fourteen executed that day, thirteen of them were part of the Nakamura Case.[4]
Founded Mountain View College
Nelson describes the founding of Mountain View College in a report published in the March 17, 1953, Youth's Instructor. They established a list of criteria based on the values of Adventist Education and then explored the vast territory of the South Philippines looking for land which met the criteria.[5]
