ISLESFORD, MAINE -- Ashley Bryan, a prolific and prize-winning children's author and illustrator who told stories of Black life, culture and folklore in such acclaimed works as "Freedom Over Me," "Beautiful Blackbird" and "Beat the Story-Drum, Pum-Pum," has died at age 98.

Simon & Schuster Children's Publishing announced that the longtime Maine resident died "peacefully" Friday in Texas, where he had been staying with relatives.

"An early, quiet, and potent force in bringing children of colour and issues of racial diversity into the canon of children's literature, he was committed to opening the eyes of children of all backgrounds to a wide range of themes through poetry, folktales, spirituals, and biblical narratives," the publisher's statement reads.

Bryan was a Harlem native who showed an early talent for drawing and for a time was the only Black student at the art school at Cooper Union in Manhattan. He served in a segregated military unit for two years during the Second World War, an experience he recounted in his memoir "Infinite Hope: A Black Artist's Journey from World War II to Peace," and resumed his art studies after the war.

Bryan worked on more than 70 books and received numerous honors, including Coretta Scott King Awards -- given for the year's best work by a Black author or illustrator -- for the folktales "Beautiful Blackbird" and "Beat the Story-Drum, Pum-Pum." He also received two lifetime achievement prizes: the Laura Ingalls Wilder Award (now known as the Children's Literature Legacy Award) and the Virginia Hamilton award.

Survivors include his brother Ernest, and "many cherished" nieces and nephews, according to Simon & Schuster.

"I am deeply saddened to learn of Ashley's passing," Maine Gov. Janet Mills said in a statement Saturday. "He was a wonderful, happy man with a deep, rich history, a great imagination, and a beautiful, childlike soul. I am so thankful I was able to spend time with him last year. Over our lunch, he spontaneously recited Langston Hughes, Shakespeare's love sonnets and other wonderful verses."

Mills had proclaimed July 13, 2020, as Ashley Frederick Bryan Day in Maine to mark Bryan's then-97th birthday. A memorial service will be held in Isleford this July 13.

Bryan also taught art, including at Dartmouth College from 1974 to 1988, before moving to Maine.

During the Second World War, he was drafted into the U.S. Army and fought in Europe, hiding drawing materials in his gas mask so he could sketch his fellow soldiers, the Bangor Daily News reported. He was part of the D-Day invasion of Normandy, France, at Omaha Beach in June 1944.

After the war, Bryan continued with his studies in Europe. He credited sketches he made of musicians at a festival in France with "opening his hand" and giving him a lasting style and approach, the Daily News reported.

"I knew if I could find the rhythm of whatever I was experiencing, that I could do all of my work and know who I am, keep trying to get to that core of who I am," Bryan said in a 2014 interview with the newspaper. "And it didn't matter if I was doing a painting, if I was doing a puppet, a sea glass panel, doing a book -- all of it is trying to tap that inner mystery of who I am."
