Wikipedia:Articles for deletion/Harold Augustin Calahan
for an author born in 1889 about such an obscure topic there are a lot of his books available. Books still being reviewed as of http://www.goodoldboat.com/bookreviews/reviews_02.html#windtide 2002 and he seems that have at least http://libcat.dartmouth.edu:2082/search/aCalahan%2C+H.+A.+%28Harold+Augustin%29%2C+b.+1889./acalahan+h+a+harold+augustin+b+1889/-3,-1,0,B/browse 8 books listed at Dartmouth library. I'm sure that some physical library searching will show he passes the  part ''The person is regarded as an important figure or is widely cited by their peers or successors.'' from the brief search I've done
