On this day in 1861, John Bagnell Bury was born in Ireland. He is best known for his 2-volume History of the Later Roman Empire, 395‑565, and also for his History of Greece to the Death of Alexander the Great. Both of them are excellent reference works for your home library.
J.B. Bury died in 1927. The History of the Later Roman Empire entered the public domain in 1998. Bill Thayer has done a monumental job of typing it in word-by-word: John Bagnall Bury: History of the Later Roman Empire.
