Barthe DeClements

Barthe DeClements (1920–2019) was an American author of children's and young adult books, best known for her debut novel "Nothing's Fair in Fifth Grade" (1981). Born in Seattle, Washington, she worked as a teacher and school counselor before turning to writing, and drew on that experience in realistic novels about school life, family difficulty and self-esteem.

Several of her books won state children's choice awards, including "Sixth Grade Can Really Kill You." She wrote linked novels featuring recurring characters, including the Elsie Edwards and Jerry Johnson series, and co-authored the novel "Double Trouble" (1987) with her son, Christopher Greimes.
