Amyotrophic lateral sclerosis (ALS) is a form of motor neuron disease, a progressive neurodegenerative disease. As the disease develops, motor neurons die and the brain loses its ability to initiate and control muscle movements.

Amyotrophy is the progressive wasting of muscle tissue.  Sclerosis is the stiffening of tissue, usually due to replacement with connective tissue.

Stephen Hawking has ALS.

Forbes magazine publishes the most famous (or infamous) list of rich people in the world. Their list only goes up to 400 so you can't check Ada Black's claim, but to own two Picassos she'd have to be very, very rich.
