EGREMONT RUSSET England 1872
JONATHAN New York late 1700's
PINK LADY Western Australia
WHITE PEARMAIN England 1200 A.D.
WINTER BANANA Indiana 1876
And, some more that I found in England:
King of The Pippins
Lane's Prince Albert

(I say 'can't', but that might mean 'not known to' - or 'only in special circumstances' - their pollen is typically considered sterile.).
A good page about this topic is here: http://www.orangepippintrees.com/articles/triploid-apple-varieties
That page lists the following as triploid apple trees:
*Belle de Boskoop
Crispin / Mutsu
The stars indicate trees I'm growing - so out of my ten apple trees, three were 'sterile'. When planning my orchard, I had to make sure to plant accompanying diploid trees fairly close to the triploid ones, and those diploids also needed at least one other diploid with overlapping flowering seasons. I also planted a crab that Robert Hart swore by called Gorlden Hornet - which has a long flowering season. I'm training it in a columnar way between some of the other trees.
Though after what Stefan has shared about 300' being an okay distance, I could likely not worry so much, and could have relied on my neighbours' crab apple tree down the street...
I am very curious how you determined that this whole list of apples are self-fertile?
