Marion Meade, who helped revive interest in Dorothy Parker, the celebrated writer and sardonic wit of the Algonquin Round Table, with her 1988 biography, died on Dec. 29 at her home in Manhattan. She was 88.

Her granddaughter Ashley Sprague confirmed the death. She said that Ms. Meade had recently had Covid-19, but that a cause had not been determined.

Ms. Meade’s “Dorothy Parker: What Fresh Hell Is This?” detailed the vibrant if difficult life of a major figure on the literary scene of the 1920s and ’30s...

Last paragraphs:

....Ms. Meade returned a few times to her best-known subject. She edited and wrote the introduction to a new edition of “The Portable Dorothy Parker” (2006). In 2014, she expanded on a 2006 Bookforum article about Mrs. Parker in a Kindle book, “The Last Days of Dorothy Parker.”

In that book, she touched on the saga of how the urn with Mrs. Parker’s ashes ended up being stowed in Manhattan in a file cabinet belonging to the veteran New York City politician Paul O’Dwyer, who was the lawyer for the writer Lillian Hellman, the literary executor of the Parker estate. (The urn, after a circuitous journey, was finally buried in 2020 at Woodlawn Cemetery in the Bronx.)

In 1987, Ms. Meade called Mr. O’Dwyer to say she was going to visit the cemetery in Westchester where she thought the urn had been buried. With her biography of Mrs. Parker complete and Ms. Hellman dead, Ms. Meade wanted to pay her respects.

“Oh, she’s not there,” Mr. O’Dwyer told her..

“Of course she is,” Ms. Meade said.

“No, no,” Mr. O’Dwyer said, “I’m looking right at her.”
