Zain Nadella was 26 years old and had been born with cerebral palsy.
Satya Nadella's message to Microsoft staff asked executives to hold the family in their thoughts and prayers while giving them space to grieve privately.
Since 2014, Nadella has focused the company on designing products to better serve users with disabilities and cited lessons he learned raising and supporting Zain.
Last year, the Children’s Hospital, where Zain received much of his treatment, joined with the Nadellas to establish the Zain Nadella Endowed Chair
It was established in Pediatric Neurosciences, as part of Seattle Children’s Center for Integrative Brain Research.
