There are several centennials to mark this year at RPI, so I've been doing a lot of research in the period 1907 to 1909. I just installed a new exhibit in the Folsom Library titled Russell Sage Laboratory 100 Years: A Glance Back at the Beginning. One hundred years ago this month, ground was broken for the construction of Russell Sage Laboratory. Funding for the new building was made possible through a $1 million gift from Margaret Olivia Sage.
