Looking at the early Wikipedia pages is fairly telling. From the first day that her page is up, Hedy Lamarr had a large section devoted to this invention[1]. But her co-inventor's Wikipedia only made a brief mention of it for the first several years[2]. It seems clear that people were interested in exaggerating her contributions in particular.
