MacArthur's wife was probably more displeased by Elizabeth Cooper-the Filipina starlet that he met in 1930 when she was 16 and became his mistress..
According to one biographer of MacArthur, William Manchester, MacArthur "showered [Cooper] with presents and bought her many lacy tea gowns, but no raincoat. She didn't need one, he told her; her duty lay in bed."
