Robert Merrifield is awarded the 1984 Nobel Prize in Biochemistry "for his development of methodology for chemical synthesis on a solid matrix".

Robert Bruce Merrifield is born in Fort Worth, TX.

After graduation in chemistry, he works for a year at the Philip R. Park Research Foundation taking care of an animal colony and assisting with growth experiments on synthetic amino acid diets. One of these experiments is one that first demonstrates that the essential amino acids must be present simultaneously for growth to occur.

The day after his graduation, Robert Merrifield and Elizabeth Furlong are married. 

He attends Pasadena Junior College.

He returns to graduate school at the UCLA chemistry department to develop microbiological methods for the quantitation of the pyrimidines.

Robert Merrifield dies in Cresskill, NJ.

One day after the marriage, they leave California for the Rockefeller Institute for Medical Research (later Rockefeller University). In the mid-60s, Merrifield's laboratory first synthesize bradykinin, insulin and other hormones. In 1969, he and a colleague synthesize the enzyme ribonuclease A. The method has stimulated progress in biochemistry, pharmacology and medicine, making possible the systematic exploration of the structural bases of the activities of enzymes, hormones and antibodies. He becomes Emeritus in 1993.

In the spring of 1923, the family settles in California where they go on to live in several cities throughout the state. Merrifield attends nine grade schools and two high schools before graduating from Montebello High School in 1939.

At the end of two years, he transfers to the University of California at Los Angeles (UCLA).
