Dorothy Crowfoot Hodgkin (1910-1994) Obituary - Reprinted from Physics Today, May, 1995 Dorothy Crowfoot Hodgkin, sole winner of the 1964 Nobel Prize in Chemistry, died at her home in Ilmington, England, on 29 July 1994. She won the Nobel Prize "for her determination by x-ray techniques of the structures of biologically important molecules." The molecular structures that she determined include those of cholesteryl iodide, penicillin, vitamin B , vitamin B coenzyme and the protein hormone insulin. Her achievements included not only these structure determinations and the scientific insight they provided but also the development of methods that made such structure determinations possible. Dorothy Crowfoot, born on 12 May 1910 in Cairo, Egypt, obtained her first degree in chemistry at Somerville College, Oxford. Her x-ray crystallographic career started with her studies of thallium dialkyl halides with Herbert M. (Tiny) Powell in the department of mineralogy and crystallography at Oxford. She obtained a PhD at Cambridge University in 1937, working from 1932 to 1936 with John Desmond Bernal, who reinforced her lifelong interest in structural biochemistry. In 1934 Bernal and Crowfoot first reported on the diffraction pattern of a protein crystal, pepsin, pointing out that protein crystals should not be dried but should be studied surrounded by their mother liquor (the standard method used since that time). The air-dried crystals gave very poor, if any, diffraction patterns, while those surrounded by mother liquor diffracted well.

Dorothy Crowfoot Hodgkin (1910-1994) Dorothy Crowfoot Hodgkin a British biochemist and crystallographer and was the sole winner of the 1964 Nobel Prize in Chemistry for determining the highly complex structure of the vitamin B-12 molecule. She used X rays to make this discovery. Knowledge of the molecular structure of vitamin B-12 has enabled scientists to better understand how the body uses this substance to build red blood cells and prevent a disease called pernicious anemia. Her achievements included not only these structure determinations and the scientific insight they provided but also the development of methods that made such structure determinations possible. Hodgkin devoted her career to studying the structures of complex substances through a method called X-ray crystallographic analysis. During the 1940's, she determined the molecular structures of cholesterol iodide, penicillin, and other related organic compounds. In 1969, she revealed the three-dimensional structure of insulin, a protein used to treat diabetes. Dorothy Crowfoot was born in Cairo, Egypt. She graduated with her first degree from Somerville College, Oxford University in 1931 and then obtained a PhD at Cambridge University in 1937.

Dr. Dorothy Crowfoot Hodgkin: Chemist, Crystallographer, Humanitarian In 1932 Dorothy Crowfoot graduated from Somerville College at Oxford with a degree in chemistry (her interest in chemistry and crystals began when she was young and was encouraged by her parents and their associates to develop this interest). While studying in the department of mineralogy and crystallography, she employed the physical science of X-ray crystallography (first developed by W. L. Bragg) to aid her in determining the structural arrangement of the atoms in simple salts and minerals such as thallium dialkyl halides. This was the first of what would be many X-ray studies. Dr. Hodgkin discovered that crystals are a solid composed of atoms arranged in a regular and repeated pattern. She later took this method one step further and used it to analyze more complex molecules. In 1933 Dr. Hodgkin began working with J. D. Bernal on her doctorate degree. Bernal strengthened her lifelong interest in structural biology. She felt that the scientific world had ceased to know any boundaries while conducting her research with him. Dr. Hodgkin stated in a published paper regarding her work with Bernal, "…we explored the crystallography of a wide variety of natural products, the structure of liquids and particularly water, Rochelle salt, isomorphous replacement and phase determination, metal and pepsin crystals, and speculated about muscular contraction." It was during this time that Dr. Hodgkin, along with Bernal, recorded the first X-ray diffraction pattern of a globular protein. These photographs were obtained from crystals of pepsin grown by John Philpot in Uppsala. These protein crystals were extremely difficult and tedious to work with in the early 1930s because of the lack of technology. Proteins are polymers, long chains of repeating units, that are larger and more complicated than other biological molecules. They perform their biological functions by folding over on themselves and assuming specific three-dimensional shapes.

Dorothy Crowfoot Hodgkin a British biochemist and crystallographer, won the 1964 Nobel Prize in Chemistry for "her determination by x-ray techniques of the structures of biologically important molecules." In other words she used x-rays to find the structural layouts of atoms and the overall molecular shape of over 100 molecules including: penicillin, vitamin B-12, vitamin D, and insulin. Hodgkin's improvements using x-ray crystallography elevated the technique to an important analytical tool. (Crystallography is a combination of physics, math, and chemistry.) Dorothy was born on May 10, 1910 in Cairo, Egypt. She obtained degrees from Oxford and Cambridge Universities. By 1934, Hodgkin correctly analyzed the molecules for cholesterol iodide. Several years later she confirmed the structure of vitamin B-12, with the help of one of the first electronic computers. Understanding the molecular structure of vitamin B-12 has helped scientists to understand how the human body uses B-12 to build red blood cells and prevent some types of anemia. Dorothy's discovery of the molecular layout of penicillin helped lead scientists to develop other antibiotics. As her discovery happened during World War II, this information aided scientists in helping to develop the antibiotics necessary to treat war injuries.

Bernal in Cambridge, photographed for the first time single crystals of a protein - pepsin. First to determine the three-dimensional structure of a complex bio-organic molecule. She determined the structure of cholesteryl iodide by x-ray diffraction in 1941-42 (published in 1945) in complete three-dimensional detail, at a time when no one else was determining complex structures in three dimensions because of the formidable calculations involved. Determined the structure of penicillin in 1944 (published in 1949), again in three-dimensional detail. Before her work there was only fragmentary and conflicting evidence on the structure, from chemical analysis, of this rather unstable molecule, which was of immense importance as an antibiotic during and immediately after World War II. Determined the structure of vitamin B-12 in 1956, using one of the first high-speed digital computers. This was by far the most complex molecule whose three-dimensional architecture had been established, and some of its unusual structural features were quite unanticipated.

Dorothy Crowfoot Hodgkin Pharmaceutical Achiever by Mary Ellen Bowden Dorothy Hodgkin On the morning in May 1940 that the results of injecting four of eight infected mice with penicillin became known, an excited Ernst Chain encountered Dorothy Hodgkin on Parks Road in Oxford. He knew the brilliant young X-ray crystallographer from her Cambridge days, and as she later recalled, he had promised: “Some day we will have some crystals for you to work on.” Dorothy Crowfoot was born in Cairo, Egypt, to English parents. Although her formal schooling took place in England, she spent a significant part of her youth in the Middle East and North Africa, where her father was a school inspector. Both her parents were authorities in archaeology, and she almost followed the family vocation; but from childhood she was fascinated by minerals and crystals. She enjoyed using a portable mineral analysis kit given to her when she became interested in analyzing pebbles she and her sister found in the stream that ran through the Crowfoots' garden in Khartoum, Sudan. When she was fifteen, her mother gave her

Dorothy Hodgkin Though born in the twentieth century, Dorothy Crowfoot Hodgkin had a typical late-nineteenth century upbringing. She was born in Cairo, Egypt, then a British colony. When Hodgkin was four, the family was back in England and World War I broke out. The parents returned to Egypt, leaving the children with family and governesses for four years. Hodgkin found an interest in chemistry and crystals, a popular hobby for women of leisure in the 1800s. But on her sixteenth birthday, she received a book by William Henry Bragg (a Nobelist in physics) about using x-rays to analyze crystals. She had found her life's work. When Hodgkin graduated from Oxford in 1932, jobs were scarce. She found a position in an x-ray crystallography lab studying biological crystals. This technique helped tease out the structure of molecules. Though diagnosed at age 24 with rheumatoid arthritis, she became one of the most skilled crystallographers of her time. In Cambridge and later at Oxford, she always chose projects that no one else thought quite possible. She ran into Ernst Chain one day, who was beaming from his recent animal trials of
