Piotr Kowalski (born 2 March 1927, Lviv – died 7 January 2004 in Paris) was a French-Polish artist, sculptor, and architect.
Piotr Kowalski worked in non-traditional materials including electronic and mechanical devices, neon art, large earth works, explosions and other natural phenomena including plant growth and gravity.
His work often expressed science or natural laws in direct and tangible ways, immediate to the senses.
A refugee of World War II, a graduate of MIT, he immigrated to France as an architect for UNESCO and spent most of the rest of his life in Paris.
Along with gallery works, he installed several large outdoors projects.
