Dorothy Crowfoot Hodgkin Crystallography is a combination of math, physics, and chemistry. It is a physical science of x-ray. Crystallography can help determine many different substance structures that can be beneficial to the world today. Dorothy Crowfoot Hodgkin was a warm and caring woman who made many contributions to the world of chemistry, such as determining by X-ray crystallography the structures of penicillin, insulin, and vitamin B-12. Dorothy Hodgkin was born on May 12, 1910 in Cairo, Egypt. Though she was born in Egypt she is actually British. John Winter and Grace Mary Crowfoot, her parents, had her. In Dorothy's early years of life she took formal schooling in England. She did spend great portion of it in the Middle East and in North Africa. John Winter, her dad, was a school inspector out in the Middle East and North Africa. John Winter and Grace Mary Crowfoot were archaeologist. According to Chemistry Heritage's website, Dorothy was more fascinated with crystals. She would carry a little portable mineral analysis kit to look at pebbles that her and her sister would fine in the stream in their family garden, in Khartoum, Sudan (ChemHeritage). It is to be said that Dorothy became interested in chemistry at age 10 because Dr. A. F., which was a friend of her parents in Sudan, gave her chemicals and helped her during her stay there (NobelPrize). When Dorothy was 15 years old, her mother, Grace gave her Sir Bragg's book, "Concerning the Nature of Things" which was published in 1925. That is how it all started. Chemistry Heritage's website goes on to say that this book discusses intricate and intriguing discussions on how scientists could use X-rays to see atoms and molecules (ChemHeritage). When Dorothy was older she would spend the seasons between school and the university with her parents. She enjoyed excavating at Jerash and drawing mosaic pavements that she almost gave up chemistry for
