Amazon founder Jeff Bezos is mourning the loss of his mother after a battle with brain illness.

Jacklyn Bezos, also known as Jackie, died peacefully at home on Thursday … she died surrounded by family in her Miami home at the age 78.

‘After a long fight with Lewy Body Dementia, she passed away today, surrounded by so many of us who loved her — her kids, grandkids, and my dad,’ Jeff Bezos wrote on Instagram.

‘I know she felt our love in those final moments. We were all so lucky to be in her life. I hold her safe in my heart forever.’

Earlier the Bezos Scholars Program confirmed her passing in their own statement, writing: ‘ A quiet final chapter to a life that taught all of us, friends and family alike, the true meaning of grit and determination, kindness and service to others.

‘Jackie’s life of service was second only to her passion for family and gathering. As a grandmother Jackie found immense joy in watching her family grow. 

‘She passed down not only traditions and stories, but also her values – kindness, resilience, and the importance of togetherness.’ 

She had been suffering with Lewy Body Dementia in 2020, with her husband Mike remaining by her side throughout the struggle.
