5. Dr. Annette Leonhard - MacDonald (Germany)

The technology industry has not always been inviting or hospitable to women. Gender imbalance in the tech industry has been recognized as an issue sine at least 2005 and, although one would have expected some improvement since then, this has not been the case. In Germany, Dr, Annette Leonhard-MacDonald is doing her part to not only break through the barriers that exist for women in the tech industry by becoming a successful entrepreneur, she's holding the door open and making room for other women in the process.
