Kathleen Schmeling, interim associate director of the Walter P. Reuther Library, commented extensively about migrant farm worker organizer Cesar E. Chavez. The Reuther Library houses Chavez\'s personal papers and an oral history he made before his death in 1993. Philip Mason, professor emeritus of the Reuther Library, is noted as an associate of Chavez during the United Farm Worker\'s (UFW) strikes against table grape growers and lettuce growers in the San Joaquin River Valley of California. Schmeling was in Lansing on March 30 with an exhibition the Reuther Library mounted called \"La Causa,\" Spanish for the cause, that \"covers 40 years of the UFW and the issues they faced,\" Schmeling said.
