Children’s book author Heather Lang has carved a niche writing picture book biographies of unsung heroines, from aviation pioneer Ruth Law to Alice Coachman, the first African-American to win an Olympic gold medal. Lang’s latest is Swimming With Sharks, about influential marine biologist Eugenie Clark. A Japanese-American widely known as the Shark Lady, Clark was the first to discover sleeping sharks, natural shark repellent, and a number of other marine species which now bear her name. (It’s even more impressive that Clark began her research during World War II.)
