Personal Life

Donald J. Cram was born on 22 April 1919, in Chester, Vermont, USA to a Scottish immigrant father, William, and a German émigré mother, Joanna. Before his birth, his parents had migrated from Ontario, Canada to rural Chester. They already had three daughters and he was their fourth born and the only male child.

Childhood & Early Life

His mother, Joanna, was a lively person with a rebel streak since childhood. William on the other hand, was a romantic cavalry officer who later worked as a successful lawyer. Unfortunately, he died of pneumonia before young Cram’s fourth birthday. As a result, his mother was left all alone to raise the four children.

Childhood & Early Life

Donald J. Cram’s education started at home when he was only four and half year old. The habit of reading was inculcated in the children by their mother. Before long, he could read different children’s books on his own.

Childhood & Early Life

Two years later, the family shifted to Brattleboro, Vermont where he grew up on Aid to Dependent Children. He had an adventurous childhood and since he was intelligent and curious, he managed to land odd jobs to support his music lessons. By his 18th birthday, he had worked at least eighteen different jobs.

Childhood & Early Life

Later in his life, he admitted that his real education happened outside classroom, “in a private world of books and brooks”. He read extensively the work of famous authors like Dickens, Kipling, Scott, Shaw, and Shakespeare and spent time with nature.

Childhood & Early Life

From 1938 to 1941, Donald J. Cram attended Rollins College, in Winter Park, Florida. Apart from regular studies, he worked as an assistant in the chemistry department, participated in theatre and chapel choir, produced a minor radio programme, and even acquired an airplane pilot’s license.

Career

During the summers of 1938–1941, he worked for the National Biscuit Company in New York City, initially as a salesman and then as an assessor of cheeses for moisture and fat content. The sales tenure helped him to learn about ethnic groups and big city street-life.

Career

At Rollins, he soon became popular for building his own chemistry equipment. He graduated with a B.S. in Chemistry in 1941 and decided to pursue an academic research career in chemistry.

Career

In 1942, he graduated from the University of Nebraska with a M.S. in Organic Chemistry, under the supervision of Dr. Norman O. Cromwell.

Career

From 1942 to 1945, when World War II was underway, he worked at Merck & Co laboratories, researching penicillin with mentor Dr. Max Tishler.

Career

Donald J. Cram made significant contributions to the chemistry of phenonium ions, asymmetric induction, carbanions, paracyclophanes, and the use of stereochemistry for explaining reaction mechanisms.

Major Works

He formulated the ‘Cram's Rule’ in 1952, which provided a methodology for calculating the result of nucleophilic attack of carbonyl compounds.

Major Works

He expanded upon Charles Pedersen's innovative synthesis of ‘crown ethers’. After Pedersen discovered crown ethers, molecules that can detain certain metallic atoms, Cram successfully built a range of molecules that could attach selective atoms and molecules to themselves owing to their corresponding three dimensional structure. This made it feasible to create chemical compounds through chemical reactions.

Major Works

He published over 400 research papers and eight books on Organic Chemistry, and mentored graduate, doctoral and post-doctoral students from 21 different countries.
