About Yedidya Lipman Leibowitz
Nechama Leibowitz's marriage to her uncle, Yedidya Lipman Leibowitz, who was 29 years her senior, caused not only wonderment, but also strife in her family (her parents were not at the chuppah).
He was a big man and blind. Nechama took care of him, and some supposed she married him specifically to enable her, as a religious woman, to be able to properly care for him.
But observers of Nechama Leibowitz point out that indeed it was for love. She felt he was the only one who could really understand her.
