Ron Rivera: Potter for Peace

Yesterday's New York Times featured a wonderful tribute to Panama RPCV Ron Rivera, who died in Nicaragua on Sept. 3 of malaria contracted while working in Nigeria.  Writes the Times:

Ron Rivera liked to call his ceramic water filters “weapons of biological mass destruction.” For 25 years he traveled to poor villages throughout Latin America, Africa and Asia teaching local potters to make what appears to be a big terra-cotta flower pot but is in fact an ingenious device for purifying water.
