Bill Gates - Help from Mom
Mary Gates played a big part early on in the success of her son Bill and Microsoft. Being on the board of United Way, she met the CEO of IBM, who was eventually introduced to Bill Gates. This encounter eventually led to Microsoft and IBM striking the software deal. Mary Gates was a well respected and influential woman who eventually helped to launch Microsoft.
Mary Maxwell Gates was never an IBM employee. She was on United Way's executive committee at the same time as then IBM CEO John Akers. Their casual conversation led to IBM's introduction to Microsoft.
IBM never meant to give anything to anyone. They were as ruthless then as Microsoft is now. IBM, along with most of the rest of the enterprise world, never imagined the microcomputer as anything but a toy. They didn't even enter the market until 6 years after Apple.
