Jean wins with her 7:36 a.m. Tuesday guess "Caltech with Charles Richter, showing off his seismographs."
In the photo above, Dr. Charles Richter makes a post-retirement visit in 1976 to the Seismology Lab at Caltech, where his Richter Magnitude Scale was in full swing for quantifying the size of earthquakes.
Richter, who died in 1985 (and is buried at Mountain View Cemetery), was a Caltech seismologist for 42 years until his retirement as professor emeritus in 1970.
A year before finishing his doctorate degree in 1928 in theoretical physics, he applied for an opening for a physicist at the new seismological laboratory.

He invented the Richter Scale in 1935.
He never won the coveted Nobel Prize, but it has been awarded to more than 30 Caltech professors and researchers.
And now the spotlight is on the Caltech Men's Basketball Team, which finally ended its 310-game, 26-year losing streak last week when the freethrow shot heard 'round the world earned the Caltech Beavers a 46-45 victory over Occidental in the Southern California Intercollegiate Athletics Conference (SCIAC).
What, you didn't know there were sports teams at Caltech? Well, look again.


Last year Caltech competed in the first annual Pasadena Collegiate Field Tournament against Art Center College of Design, Fuller Theological Seminary, Le Cordon Bleu College of Culinary Arts, Pacific Oaks College and Pasadena City College:
Caltech seized the day!
The 2011 Pasadena Collegiate Field Tournament will be on Friday, April 8, at 6:30 p.m. at Pasadena City College's Robinson Stadium. Come cheer on your favorites!
Many thanks to Caltech for the photos of Dr. Richter and the Men's Basketball Team.
