Giacomo Luigi Ciamician (August 27, 1857 – January 2, 1922) was an Italian photochemist of Armenian descent[2] and an Italian senator.[3]

He was born in Trieste, Italy (then part of Austria) from Armenian parents.

Ciamician was an early researcher in the area of photochemistry, where from 1900 to 1914 he published 40 notes, and 9 memoirs.He received his Ph.D. from the Universität Giessen. His first photochemistry experiment was published in 1886 and was titled "On the conversion of quinone into quinol.[2] He may be regarded as the father of the solar panel. He had one on his roof that illuminated a single light bulb in his laboratory. In 1912 he presented a paper before the 8th International Congress on Applied Chemistry in which he predicted the world's using clean energy supplied by solar power:

"On the arid lands there will spring up industrial colonies without smoke and without smokestacks; forests of glass tubes will extend over the plains and glass buildings will rise everywhere; inside of these will take place the photochemical processes that hitherto have been the guarded secret of the plants, but that will have been mastered by human industry which will know how to make them bear even more abundant fruit than nature, for nature is not in a hurry and mankind is. And if in a distant future the supply of coal becomes completely exhausted, civilization will not be checked by that, for life and civilization will continue as long as the sun shines!'"'[4]

He received the honorary Doctor of Laws (DLL) from the University of Glasgow in June 1901.[5]

He died in Bologna, Italy.
