Who is William Mack Knight?

William Mack Knight was born in the United States of America, and is an entrepreneur as well as a technology industry executive, but probably better known for his two-year relationship with actress Emma Watson. She is particularly noted for her portrayal of the character Hermione Granger in the “Harry Potter” film series.

The Wealth of William Mack Knight

William Mack Knight has a net worth estimated to be over $150,000, though this may be an understatement, through lack of clarity with his Silicon Valley position. He probably benefitted from the wealth of Emma Watson during their time together too, as she has a net worth estimated to be over $80 million.


Education and Career

William enrolled into Princeton University and studied for a degree in Evolutionary Biology and Ecology. The Ivy League university was founded in 1746 and is the fourth oldest higher education institution in the US, which was chartered before the American Revolution. It started out as the College of New Jersey, before becoming Princeton University in 1896. The university is often ranked among the top two in national universities, based on the US News & World Report, responsible for creating numerous achievers in various professions.

After graduating, he enrolled at Columbia Business School to complete a Master’s degree in Business Administration (MBA). The school is a member of the Ivy League Columbia University, and is one of the oldest as well as one of the most selective business schools in the world, ranked among the top for its business program. Following the completion of his degree, he began working in Silicon Valley with Medallia Professional Services, which is a company that specializes in customer support, serving as a Senior Manager.

Ex-Girlfriend Emma Watson

Emma was born in Paris, though her family later moved to Oxfordshire, England where she was raised. She attended Dragon School, and at a young age aspired to be an actress, training as a student at Stagecoach Theatre Arts. The school was founded in 1988, and is now the largest network of performing arts schools for children, with over 48,000 students enrolled on a regular basis. She mainly performed in school plays, and trained during her free time.

She got her big break when she was cast in the “Harry Potter” films as Hermione Granger. The films are based on the novels by author JK Rowling, following the titular character and their friends as they navigate different adventures in a world of magic. She’s been a part of all the “Harry Potter” films, including “Harry Potter and the Philosopher’s Stone” up to “Harry Potter and the Deathly Hallows – Part 2” making up the main star trio along with Danielle Radcliffe and Rupert Grint. The series of films would become the third highest grossing worldwide. With all of her commitments to the franchise, she still worked on other projects during her free time.

Emma Watson Post-Harry Potter

After the last “Harry Potter” film, she started took supporting roles in several films. In 2012, she starred in “The Perks of Being a Wallflower” which is a coming of age story based on the novel of the same name, and follows the story of a teenager who goes through his first year of high school. The following year she worked on “The Bling Ring” which is based on the article “The Suspects Wore Louboutins” by “Vanity Fair”, telling the story of a gang known as the Bling Ring using the internet to track celebrities and steal from their homes.

During the same year, she played an exaggerated version of herself in “This is the End”. In 2017, she portrayed the character Belle in the live action adaptation of “Beauty in the Beast”. While working on acting, she split her time and continued her education, completing a degree in English literature from Brown University. She has also done modelling for companies such as Burberry and Lancome. She is a UN Women Goodwill Ambassador, and helped launch the HeForShe campaign which advocates gender equality.

Personal Life

Knight met Watson in 2015 and they began dating, with Emma liking him due to his lack of any association with Hollywood – she previously dated British Rugby player Matthew Janney for a year before she met Knight. The two shared a lot of interests, including a love for travel, adventure, and photography. She also maintains a fit body, spending a significant amount of time doing fitness-related activities. He also showed a sense of humor based on his social media accounts, though all the attention led him to set his accounts to private. The two have been spotted going to restaurants, watching musicals, and many other activities.

In 2017, it was reported that they had split up and were last seen together in New York. The relationship was reportedly serious as he introduced her to his parents, but things didn’t work out. Watson has refused to comment about their relationship, as she prefers to keep her privacy and be consistent about it.
