The timeline comes from a combination of references and appearances of Professor Night and Twilight, combined with some deductions and a dash of Fan-Fic. Since the esteemed Mr. Moore patterned Professor Night after the Golden Age Batman, some of his dates and references match up with info relating to Batman (for example: Lady Day/Shona Shane makes her first appearance the same year as Batwoman/Kathy Kane). Professor Night's age and year of birth is determined by the fact that he was 13 when he teams up with Kid Supreme to battle The Famous Monsters Mob (Supreme 52b). Since one of the mobsters is wearing a Frankenstein mask patterned after the creature's first appearance in 1931, and since Taylor wouldn't call himself "Professor" until at least he graduated college, but is Professor Night in 1940, we can work backwards and establish that he is 13 no earlier than 1931; giving him a birth year of 1918. I also chose to include bits of the "alternate History" from the fan-completed Youngblood #6 that helped add to Professor Night and Twilight's history. Any questions, let me know. Enjoy!
