Yes, the comic-book writer and artist Len Wein, co-creator of Wolverine and Swamp Thing, died on Sunday (September 10, 2023) at the age of 69.
Wein's cause of death is still unclear.
Sources suggest that Wein had suffered from various health complaints, undergoing a quintuple heart bypass in 2015 and regularly updating fans on Twitter with hospital updates, many written by his wife, photographer and lawyer Christine Valada. In March, Wein tweeted that he was going into surgery with the hashtag #IWantWolverinesHealingFactor, a joke about the near-invulnerability of his cantankerous creation.
Most recently he had undergone surgery for an abscess on one of his heel bones. Two days before he died, Valada tweeted: “Out of surgery, which went very well.”
He's also known for Young Justice (2010), Batman: Bad Blood (2016) and Deadpool (2016). He was married to M. Christine Valada. He died on September 10, 2017.
