Charles McNider is the original Doctor Mid-Nite appearing in All American Comics #25 (April 1941) in the Golden Age of Comic Books and is a common member of the Justice Society of America. McNider, a young surgeon, was blinded when a grenade went off in front of him caused by gangster "Killer" Maroni, but he found that he could see in the dark. He made special goggles that allowed him to see in the daylight, and decided to use his special power to fight crime. In his civilian identity, he pretends to be a helpless blind man.
As the aging McNider spent less time in action, Beth Chapel, a medical doctor, stepped into the role of Doctor Midnight. Beth Chapel was a native of Orangeburg, South Carolina, with a pastor father, a mother who sang in the church choir, and four brothers. Chapel first appeared when Jade of Infinity, Inc. was rushed to her hospital for treatment after encountering Mister Bones' cyanide touch. During the onset of the Crisis on Infinite Earths, Beth was blinded by an oxygen explosion, only to be rescued by Hourman's son Rick Tyler, who had taken McNider's drug that enhances ability to see in the dark. Beth used the formula to similarly treat her blindness, and she and Rick assume the mantles of their predecessors as Doctor Midnight and Hourman, with her mother crafting a super hero costume from a choir robe. Along with a new Wildcat, Chapel and Tyler applied for membership in Infinity, Inc, eventually gaining admission; however, the association was short-lived, as Infinity, Inc. disbanded shortly thereafter, though Chapel and Tyler began a romantic relationship during their tenure.
Doctor Mid-Nite (Pieter Cross), much like the original version of Doctor Mid-Nite, he has exhibited the same basic features: a cowled costume featuring a crescent moon symbol, keen ability to see in the darkness at the cost of near or total blindness in sunlight, the use of special visors and “blackout” smoke bombs to gain tactical advantage in combat, a high degree of skill in martial arts, and jobs as physicians serving both normal human beings and "metahuman" superheroes. Additionally, two of the doctors have been accompanied by sidekick owls.
