Beginner Books is the Random House imprint for young children ages 3–9, co-founded by Phyllis Cerf with Ted Geisel, more often known as Dr. Seuss, and his wife Helen Palmer Geisel. Their first book was Dr. Seuss's The Cat in the Hat (1957). Cerf compiled a list of 379 words as the basic vocabulary for young readers, along with another twenty slightly harder "emergency" words. No more than 200 words were taken from that list to write The Cat in the Hat. Subsequent books in the series were modeled on the same requirement.
Beginner Books had only four titles in their catalog in 1958. Two years later they were earning a million dollars a year and Random House was the largest publisher of children's books in America.
When Theodor Seuss Geisel illustrated his own stories he wrote as Dr. Seuss. When others created the illustrations, he used either the pseudonym Theo LeSieg or Rosetta Stone. Other authors of early Beginner Books were Robert M. Lopshire, Bennett Cerf, Al Perkins, Helen Palmer Geisel who wrote as Helen Palmer, Philip Dey Eastman, Stan and Jan Berenstain, Benjamin Elkin and Marion Holland.
Early Beginner Books employed many famous illustrators including the aforementioned Theodor Geisel, P.D. Eastman, Stan and Jan Berenstain, and Robert Lopshire. Roy McKie was also an illustrator.
