Why are Harvard beets called Harvard beets?

It seems that the origin of the name "Harvard beets" is still unknown. There are theories though (Encyclopedia of American Food and Drink by John F. Mariani) that the dish was created three centuries ago at an English tavern called Harwood's. Presumably, one of its customers, a Russian emigre opened a restaurant up in Boston under the same name in 1846. But since he kept pronouncing his restaurant's name like "Harvard," so the dish he brought from England became known as 'Harvard beets.'
