     Grace was  educated at Vassar College and Yale.  She got her doctor's degree in 1934.  She taught at Vassar College. Grace got married to a man named Vincent Hopper.  They had no children.  She served in the United States Naval Reserve. She joined the Navy in World War II.She retired 1986 with the rank of the Rear Admiral.
     She developed  the “cobol”  [a computer language] in 1952.   She developed a compiler which allowed a computer to write programming in five minutes.  The invention was used for computer language  instead of all numbers.   She made it so you could use words on the computer instead of numbers. It took a month for her to make the invention.
She had no help at all on her invention. She did it on her own. 
     Her invention was very popular because if it wasn’t for her,  you could not e-mail your friends.
