The Nature of Code

For my grandmother Bella Manel Greenfield

October 13, 1915–April 3, 2010

Bella Manel was born in New York City. A pioneering woman in mathematics, she earned her PhD in 1939 from New York University under the supervision of Richard Courant. She worked for Ramo-Wooldridge and at the RAND Corporation with Richard Bellman. Later, she taught mathematics at the College of Notre Dame (now Notre Dame de Namur University) in Belmont, California, and at the University of California, Los Angeles. The Bella Manel Prize for outstanding graduate work by a woman or minority was established at New York University’s Courant Institute in 1995.
