What is david wozniak true story?

David Wozniak is the real-life inspiration behind the 2014 comedy-drama film "Delivery Man," starring Vince Vaughn. He is a Canadian man who unwittingly became the biological father of 533 children after anonymously donating sperm to a fertility clinic in the 1980s and 1990s.

In 2011, Wozniak's children filed a lawsuit to reveal his identity and the clinic's records. The court ruled in favor of the children, and Wozniak was identified publicly. He eventually met with some of his children and maintains a positive relationship with them.

Wozniak's story has sparked debates about the ethics of anonymous sperm donation and the rights of donor-conceived children to information about their biological origins. Despite the legal and ethical controversies surrounding his story, Wozniak has expressed happiness in meeting some of his biological children and has become an advocate for the importance of family and fatherhood.
