		<p>Irving Adler was born in 1913 in New York City. He received his B.S.
		  from City College of New York in 1931, and later and M.A., and Ph.D in
		  Mathematics from Columbia University. Irving Adler taught high school math in
		  New York for twenty years and later taught math at Columbia and Bennington
		  College in Vermont. He married Ruth Adler, his frequent collaborator on many
		  books, in 1935; Ruth Adler aslo did the illustrations for many of Irving
		  Adler's books and others were done by their daughter Peggy Adler. Irving Adler
		  began writing science books for children in 1952 with the aim of presenting
		  "scientific ideas simply" so they can be "readily understood" by young readers.
		  The Adler's "Reason Why" series covered many topics in science and math and
		  were written with a "simplicity of style" that provided accurate, up-to-date
		  information that not only told of whwat is known about a given topic but how
		  the facts were reasoned and established. After Ruth Adler's death in 1968,
		  Irving Adler continued to write; he collaborated on one book
		  <emph render="italic">Language and Man</emph>, with his second wife, Joyce
		  Adler. Irving Adler believed that learning about science could be fun and that
		  one should never "write down" to children. Throughout his long and prolific
		  career, Irving Adler has writte dozens of books on science and math for
		  children and several for adults. His works have been praised by critics for
		  "presenting complex ideas in [an] accurate, comprehensible, and interesting
		  fashion," and "for introducing young readers to math and science" with a unique
		  "clarity and lack of condescension."</p>
