Gerhard Ertl

Gerhard Ertl (born October 10, 1936), German physicist and a Professor emeritus at the Department of Physical Chemistry, Fritz-Haber-Institut der Max-Planck-Gesellschaft in Berlin, Germany, authentic, autographed 4 x 6 glossy photograph featuring the Nobel Prize.

He was awarded the 2007 Nobel Prize in Chemistry for his studies of chemical processes on solid surfaces. The Nobel academy said Ertl provided a detailed description of how chemical reactions take place on surfaces. His findings applied in both academic studies and industrial development, the academy said. “Surface chemistry can even explain the destruction of the ozone layer, as vital steps in the reaction actually take place on the surfaces of small crystals of ice in the stratosphere,” the award citation reads.

The photograph is signed in blue ink and is in excellent condition.
