In the memory of late Dr. Blackmer

Dong-Gill,

I am not aware of a memorial service for Dr. Blackmer on campus. A memorial service was held Jan. 31 in Jefferson. In lieu of flowers, thefamily suggests donations to a scholarship fund: Fred Blackmer Agriculture Scholarship, c/o JSCS Foundation, Home State Bank, 115 StateSt., Jefferson, IA 50129. Also his family has set up a memorial Webpage for him at: http://blackmer.no-ip.org/.Regards,
