 Mallon built Bird's BioRite plant in Mexico, BioRite, a product involved in oil drilling. By the way, I got an email today talking about the Mexico holdings of two companies, Halliburton and Schlumberger, both of which figure in this story. Dresser Industries was bought by Halliburton in 1998, and at that time, the Kellogg subsidiary of Dresser became part of Brown and Root. Brown and Root itself had been bought by Halliburton in 1962, the year before President Kennedy's death.
