1 00:00:00,000 --> 00:00:27,579 Hi everyone! Today we're going to remember who Dorothy Crawford-Hodgkin was and what did she 2 00:00:27,579 --> 00:00:36,619 achieve. Dorothy studied science all her life but she was specialized in chemistry. Thanks to her 3 00:00:36,619 --> 00:00:44,179 dishes spirit not only did she achieve a brilliant discovery but also an amazing group of them that 4 00:00:44,179 --> 00:00:52,219 won her the Nobel Prize in Chemistry in 1964. Let's go back to 1910 when Dorothy 5 00:00:52,219 --> 00:01:04,450 was born. My interest in science, especially in chemistry, started when I 6 00:01:04,450 --> 00:01:11,890 was 10. At that age I was covering easy projects in my house and when I was 16 I 7 00:01:11,890 --> 00:01:17,709 wrote a book called The Nature of the Things, written by William H. Braque, 8 00:01:17,709 --> 00:01:25,469 novel in physics in 1950. That book dealt about the amazing experimental technique 9 00:01:25,469 --> 00:01:32,090 X-ray crystallography that allowed to see three-dimensional structure of a 10 00:01:32,090 --> 00:01:42,310 molecule and its atoms. Since I read the book I was much more interested. British 11 00:01:42,310 --> 00:01:47,709 women at that time, including me, were fighting for coeducation, a synopsis for 12 00:01:47,709 --> 00:01:53,590 University only admitted one female student for every five male students and 13 00:01:53,590 --> 00:02:02,230 in Cambridge one female student for every nine male students. Girls couldn't 14 00:02:02,230 --> 00:02:07,510 participate in debates or go to the restaurants unless accompanied by a boy. 15 00:02:07,510 --> 00:02:14,810 I got my studies in Oxford University and there I went to a conference given by 16 00:02:14,810 --> 00:02:22,810 John D. Bernal, considered one of the most important scientists of the 20th century, 17 00:02:22,810 --> 00:02:30,409 which inspired me. I decided to specialize in the field of X-ray crystallography and in order to do 18 00:02:30,409 --> 00:02:39,610 so I needed to move to Cambridge University and there get my doctoral thesis. X-ray crystallography 19 00:02:39,610 --> 00:02:45,509 was a great advance for scientists. From now on we could use this technique to 20 00:02:45,509 --> 00:02:52,750 study biological substances, from viruses to vitamins, and this caused a 21 00:02:52,750 --> 00:02:59,530 revolution in public health. When I finished my thesis I went back to 22 00:02:59,530 --> 00:03:05,949 Oxford and there I tried to figure out the structure of the insulin. The 23 00:03:05,949 --> 00:03:14,789 The molecule was so complicated that it took 34 years to rebuild its architecture. 24 00:03:14,789 --> 00:03:18,710 Later on I was married and I had three children. 25 00:03:18,710 --> 00:03:25,430 I needed to juggle with my family and my work because my husband was away all the week working 26 00:03:25,430 --> 00:03:32,520 in adult education in North England and later in Africa. 27 00:03:32,520 --> 00:03:39,159 When I was 28, doctors found me that I had rheumatoid arthritis and I have to spend most 28 00:03:39,159 --> 00:03:45,280 of my time in a wheelchair and I need to make delicate operations which involve with my 29 00:03:45,280 --> 00:03:46,280 work. 30 00:03:46,280 --> 00:03:54,639 But this didn't stop me searching more, because then I managed to reveal the three-dimensional 31 00:03:54,639 --> 00:04:01,439 structure of numerous important biomolecules that organoscapists couldn't decipher, such 32 00:04:01,439 --> 00:04:08,840 as cholesterol, visual vitamin or insulin. Then I was admitted in Royal Society of 33 00:04:08,840 --> 00:04:16,199 London, the most prestigious national scientific association that with 287 34 00:04:16,199 --> 00:04:24,120 years of history only choose a woman for the third time. One day I managed to work 35 00:04:24,120 --> 00:04:30,360 with Rosalind Franklin when I discovered the three-dimensional structure of the DNA, 36 00:04:30,360 --> 00:04:36,240 the most important molecule at that age. I was denied a visa to enter in the United 37 00:04:36,240 --> 00:04:42,720 States to attend scientific conferences because I had belonged to the Science 38 00:04:42,720 --> 00:04:49,300 for Peace, a group that included some communists, but later with the 39 00:04:49,300 --> 00:04:54,000 special permission of the Attorney General I was allowed. This was very 40 00:04:54,000 --> 00:05:00,839 important for me because in 1964 I was awarded the Nobel Prize in chemistry for 41 00:05:00,839 --> 00:05:06,199 the determination of the structure of many biological substances by x-rays. 42 00:05:06,199 --> 00:05:14,879 The prize also got the honor to be granted alone and when I was 54 I was 43 00:05:14,879 --> 00:05:20,680 the third woman and the first British woman to win a Nobel Prize in science. 44 00:05:20,680 --> 00:05:30,680 Also, Oxford University awarded a first-class degree to a woman only for the third time in its history. 45 00:05:30,680 --> 00:05:38,759 Rheumatoid arthritis, which... 46 00:05:43,759 --> 00:05:47,759 When I was 28, doctors found me like that... 47 00:05:47,759 --> 00:05:54,759 Now, we could use this technique to study biological substances, to study... 48 00:05:54,759 --> 00:05:59,759 Ay no, mierda. Es que si no estoy haciendo algo me pongo nerviosa, párale y bórralo. 49 00:05:59,759 --> 00:06:10,759 This was very important for me because in 1964 I was awarded the Nobel Prize in Chemistry for the determination of... 50 00:06:10,759 --> 00:06:33,069 Then, I was admitted in the Royal Society of London, the most prestigious national scientific 51 00:06:33,069 --> 00:06:44,850 association that, with 287 years of history, only chose a woman for the third time, then 52 00:06:44,850 --> 00:06:55,730 I was admitted in the Royal Society of London, the most prestigious national scientific. 53 00:06:55,730 --> 00:07:02,829 I decided to specialize in the field of X-ray crystallography, and in order to do so I needed 54 00:07:02,829 --> 00:07:11,410 to move to Cambridge University for getting my doctoral thesis.
