Nicholas Tyson Klug used to create art in many forms — painting, drawing, cooking — before he was diagnosed with primary progressive multiple sclerosis in 2005. Klug has shown painting exhibits before, but none since he was forced to move to Philadelphia from his home in Michigan to receive care for his disability. In February, he opened up an exhibit at the Old City Jewish Arts Center — the first exhibit since his diagnosis —and he’s excited to share it with the city.
