Doctor Beth Chapel, was a medical intern from South Carolina, and protégé of Charles McNider in Los Angeles. She had known about his double identity and his special sight for some time when she was first introduced to his super-hero lifestyle. It was when Jade was rushed to the hospital for treatment against Mr. Bones' cyanide touch. (Infinity, Inc. #19) McNider tried to keep his secret identity from Beth even though later she admitted that she'd already guessed it. She also helped McNider treat Nuklon and that day she had lunch with them as well as Rex Tyler (Hourman) and his son, Rick. Just then an earthquake struck and Beth leapt into action to protect the hospital's patients. She was caught in a fiery blast and although she was saved by Rick, she had lost her sight. (#20)
Chapel returned home to Orangeburg to recover. It was difficult; her father was a minister and she had left the church long ago. As Hourman II, Rick Tyler came to her family home and met her brother, John. He said that the Justice Society and Infinity had disappeared. This was during the first Crisis, and soon she and Rick were beset by the shadow demons of the Anti-Monitor. Her life was on the line and she prayed for her sight to return. Fate intervened and in the darkness of the shadow creatures, Beth found that like Charles McNider, she too could see in the dark. They drove off the shadows and when her parents returned home, she told them everything. Her mother helped create a costume for Beth, but her father disapproved of her decision to become Doctor Midnight. She left immediately with Hourman. (#21)
The Crisis was in full swing and the new heroes helped defend Orangeburg from the destruction—including Civil War soldiers and dinosaurs from the past. (#22)
Along with Wildcat II, they applied for membership in Infinity, Inc., but were not immediately accepted. Eventually they were admitted, but their careers were short-lived.
Beth had begun a romantic relationship with Rick Tyler
After Infinity disbanded, Doctor Midnight and Wildcat were recruited by the U.S. government for a mission to defeat Eclipso. Both women died on that mission along with the Creeper, Commander Steel, Peacemaker and Major Victory. (Eclipso #13)
Earth-2, Post-Infinite Crisis
After the Crisis on Infinite Earths, the original Earth Two was merged into all other surviving Earths. After the Infinite Crisis, the multiverse of the DC Universe was restored, there was again an Earth-2. Their history seemingly unfolded as if the first Crisis had never happened (picking up approximately after Infinity, Inc. #24). On it, Infinity Inc. and the Justice Society merged to form Justice Society Infinity, and Beth Chapel remained a member. (JSA Kingdom Come Special: The Kingdom #1)
