The 1970s brought a wave of expansion as Lilly acquired facilities in the Municipality of Carolina, transforming former factories into thriving pharmaceutical centers. New medicines like Vancomycin, Oncovin, and Keflex flowed from Puerto Rican hands to patients worldwide. Behind every batch stood employees who worked tirelessly to master new technologies and uphold Lilly’s standards. The company also introduced various benefit programs while a group of employees launched the Eli Lilly Employees Credit Union, ensuring that the jobs created weren’t just temporary posts but stepping stones for Puerto Rican families. By the end of the decade, Lilly was firmly rooted in the island’s economy, and its employees had become ambassadors of quality and innovation.
