O'Neil did internationally known work on replication in distributed databases, page replacement strategies for databases, SQL isolation, and database indexing strategies, as detailed on his Wikipedia page. O'Neil was known for his gregarious and blunt manner, as well as his contagious sense of humor. He liked to brag that he "took humor very seriously." He was the Chief Fool of his "humor group" and had many fond memories of his fellow fools. He is survived by his wife and UMass colleague, Elizabeth O'Neil, 2 children, and 4 grandchildren. All of them are nerds as well. In lieu of flowers, please donate to the Salvation Army, his favorite charity.
