"For the discovery of Iysosomes. These are membrane bound subcellular particles containing hydrolytic enzymes and other biologically active substances. He isolated the characterized Iysosomes chemically and ultrastructurally. These subcellular particles play an important role in physiological and pathological processes. Their discovery has led to a better understanding of many disease processes and has opened innumerable new avenues of research."
