In 2020, a legendary Batman writer sadly passed away. His name is Dennis O'Neil and he's one of the most important writers of the Batman comics.
By the time that Dennis O'Neil started writing Batman comics in the 1960's, the Batman comics were struggling. Although the 60's helped introduce Batman to TV fans, the character was struggling to stay relevant in the comics. Batman's creator and original writer, Bill Finger, was no longer regularly writing Batman comics. By that time, the Batman comics were going through a weird phase. Batman had gone on weird sci-fi adventures, the Bat-family was growing and growing and Batman barely seemed like a detective.
Dennis O'Neil came along and tried to change the way Batman was being written. He made Batman act like a real detective, for the first time in years. He made Batman more serious and mysterious, without making him too dark or intense. Dennis O'Neil also made several changed to the rogues gallery and even created some villains of his own.
Dennis O'Neil's biggest creation was the character of Ra's al Ghul. He created the character, along with Julius Schwartz and Neal Adams. Ra's al Ghul was an old, but very wise and clever man, who is arguably the most imposing threat Batman has ever gone against. Ra's al Ghul became such a beloved opponent for Batman, that he became Batman's second arch-enemy. In addition to that, Ra's al Ghul started appearing in other media, including cartoons and he even appeared in the blockbuster-hit Batman Begins.
Dennis O'Neil also created Ra's al Ghul's daughter, Talia al Ghul. Talia was a character, who was torn between being like her villainous father or following Batman's good example. Talia became one of Batman's main love-interests and even became the mother of Bruce Wayne's son, Damian Wayne. Although Dennis O'Neil didn't create Damian, he did create Talia, so it could be argued that Damian wouldn't exist without Dennis O'Neil.
Dennis O'Neil was a highly-influential writer. A lot of Batman's biggest story-arcs, from recent decades, wouldn't of happened if it wasn't for him. He was an undeniably important part of Batman's legacy and his positive contributions will not be forgotten or ignored. His last Batman-related role was appearing in a video celebrating Batman's 80th anniversary. In the video, several people involved with Batman wished Batman a happy 80th birthday. Out of all of the people included in the video, I believe Dennis O'Neil was the most important. After all, Batman wouldn't be as popular, without his great work.
Thank you, Dennis O'Neil, for all that you've done for comics and for Batman. Rest well, old chum.
