SCIENTISTS

     Robert Hare 

Robert D. Hare, C.M. (born in Calgary, Alberta, Canada, 1934), is a researcher in the field of criminal psychology. He developed the Hare Psychopathy Checklist (PCL-Revised), used to assess cases of psychopathy. Hare advises the FBI's Child Abduction and Serial Murder Investigative Resources Center (CASMIRC) and consults for various British and North American prison services.
Hare received his Ph.D. in experimental psychology at University of Western Ontario (1963). He is professor emeritus of the University of British Columbia where his studies center on psychopathology and psychophysiology. He was invested as a Member of the Order of Canada on December 30, 2010.
His research led him to The Mask of Sanity by American psychiatrist Hervey M. Cleckley, which played a pivotal role in the concept of psychopathy he applied and developed.
In the 1970s he published Psychopathy: Theory and Research, summarizing the state of the field, and became internationally influential in reviving and shaping the concept.
Hare's research on the causes of psychopathy focused initially on whether such persons show abnormal patterns of anticipation or response (such as low levels of anxiety or high impulsiveness) to aversive stimuli ('punishments' such as mild but painful electric shocks) or pleasant stimuli ('rewards', such as a slide of a naked body).
Hare wrote a popular science bestseller published in 1993 entitled Without Conscience: The Disturbing World of the Psychopaths Among Us (reissued 1999). He describes psychopaths as 'social predators', while pointing out that most don't commit murder.
Hare also co-authored the bestselling Snakes in Suits: When Psychopaths Go to Work (2006) with organizational psychologist and human resources consultant Paul Babiak, is a portrayal of the disruptions caused when psychopaths enter the workplace.
Hare appeared for several minutes in the 2003/4 award-winning documentary film The Corporation, discussing whether his criteria for psychopathy could be said to apply to modern business as a legal personality, appearing to conclude that many of them would apply by definition.


     Steve Mann 

Steve Mann was born on 1962 in Hamilton, Ontario, Canada. He is a researcher and inventor best known for his work on computational photography, particularly wearable computing and high dynamic range imaging.
Mann holds a PhD in Media Arts (1997) from the Massachusetts Institute of Technology and a B.Sc., B.Eng. and M.Eng. from McMaster University in 1987,1989 and 1992, respectively. He was also inducted into the McMaster University Alumni Hall of Fame, Alumni Gallery 2004, in recognition of his career as an inventor and teacher. While at MIT, in then Director Nicholas Negroponte's words "Steve Mann ... brought the seed" that founded the Wearable Computing group in the Media Lab and "Steve Mann is the perfect example of someone ... who persisted in his vision and ended up founding a new discipline." In 2004 he was named the recipient of the 2004 Leonardo Award for Excellence for his article "Existential Technology," published in Leonardo 36:1.
He is also General Chair of the IEEE International Symposium on Technology and Society, Associate Editor of IEEE Technology and Society, is a licensed Professional Engineer, and Senior Member of the IEEE.
Many of Mann's inventions pertain to the field of computational photography:
Chirplet transform, Video Orbits, Comparametric Equations, Integral kinematics and integral kinesiology, Hydraulophone, Natural User Interface, Scratch input, an acoustic-based method of Human-Computer Interaction (HCI) that takes advantage of the characteristic sound produced when a finger nail, stick, or other object strikes or is dragged over a surface, such as a table or wall, Telepointer, Sensory Singularity, Sousveillance and cyborg-logging, Surveilluminescent wand.
Mann has been referred to as the "father of wearable computing", having created the first general-purpose wearable computer, in contrast to previous wearable devices that perform one specific function such as time-keeping (e.g. wristwatch), calculations (e.g. wearable abacus), such as Edward O. Thorp and Claude Shannon's, timing devices concealed in shoes cigarette packs for cheating at a game of roulette.

     Sidney Altman 

Sidney Altman was born on 1939 in Montreal, Canada, and he  is a Canadian and American molecular biologist, who is the Sterling Professor of Molecular, Cellular, and Developmental Biology and Chemistry at Yale University. In 1989 he shared the Nobel Prize in Chemistry with Thomas R. Cech for their work on the catalytic properties of RNA.
As Altman reached adulthood, the family's financial situation had become secure enough that he was able to pursue a college education. He went to the United States to study physics at the Massachusetts Institute of Technology. While at MIT, he was a member of the ice hockey team. After achieving his bachelor's degree from MIT in 1960, Altman spent 18 months as a graduate student in physics at Columbia University. Due to personal concerns and the lack of opportunity for beginning graduate students to participate in laboratory work, he left the program without completing the degree. Some months later, he enrolled as a graduate student in biophysics at the University of Colorado Medical Center. His project was a study of the effects of acridines on the replication of bacteriophage T4 DNA. He received his Ph.D. in biophysics from the University of Colorado in 1967 with thesis advisor Leonard Lerman; Lerman went in 1967 to Vanderbilt University, where Altman worked briefly as a researcher in molecular biology before leaving for Harvard.
Altman was married to Ann M. Körner (daughter of Stephan Körner) in 1972. They are the parents of two children, Daniel and Leah.  Having lived primarily in the United States since departing Montreal to attend MIT in 1958, Altman became a U.S. citizen in 1984, maintaining dual citizenship as a Canadian citizen as well.
After receiving his Ph.D., Altman embarked upon the first of two research fellowships. He joined Matthew Meselson's laboratory at Harvard University to study a DNA endonuclease involved in the replication and recombination of T4 DNA. Later, at the MRC Laboratory of Molecular Biology in Cambridge, England, Altman started the work that led to the discovery of RNase P and the enzymatic properties of the RNA subunit of that enzyme. John D. Smith, as well as several postdoctoral colleagues, provided Altman with very good advice that enabled him to test his ideas. "The discovery of the first radiochemically pure precursor to a tRNA molecule enabled me to get a job as an assistant professor at Yale University in 1971, a difficult time to get any job at all".
While at Yale, Altman's Nobel Prize work came with the analysis of the catalytic properties of the ribozyme RNase P, a ribonucleoprotein particle consisting of both a structural RNA molecule and one (in prokaryotes) or more proteins.


     Sir Frederick Grant Banting 

Sir Frederick Grant Banting, KBE, MC, FRS, FRSC (November 14, 1891 – February 21, 1941) was a Canadian medical scientist, physician, painter and Nobel laureate noted as the first person that used insulin on humans.

In 1923 Banting and John James Rickard Macleod received the Nobel Prize in Medicine. Banting shared the award money with his colleague, Dr. Charles Best. As of September 2011, Banting, who received the Nobel Prize at age 32, remains the youngest Nobel laureate in the area of Physiology/Medicine. The Canadian government gave him a lifetime annuity to work on his research. In 1934 he was knighted by King George V. In 2004, Frederick Banting was voted fourth place on The Greatest Canadian.
Frederick Grant Banting  was born in Alliston (Ontario, Canada) on 14 November 1891. He was the youngest of five children of William Thompson Banting and Margaret Grant. He completed his studies in Alliston. It began theology at the University of Toronto, which soon changed medicine. He graduated in 1916.
He was part of the Canadian Army Medical Corps and participated in the First World War in France. After the end of the war, in 1919, he returned to Canada.
He earned his doctorate in 1922. Soon he was already very interested in diabetes. Since the late nineteenth century scientists had noticed the relationship between the pancreas and diabetes. Some studies indicated that the disease was caused by a deficiency of a hormone secreted by the islets of Langerhans.Schafer called it "insulin" and supposedly exercised control over sugar metabolism, so that their absence caused this increase in blood and urine.He got in touch with J.J.R. Macleod, professor of physiology at the University of Toronto, who facilitated it necessary to investigate in his laboratory.In August 1921 they administered insulin from the islets of Langerhans in diabetic dogs descended checking sugar levels in blood and urine disappeared and the typical symptoms of the disease.Banting and Macleod received the Nobel Prize for Medicine in 1923.In 1930, the Canadian Parliament granted aid to Banting for the installation of a research laboratory and he was made an honorary doctor of Toronto General Hospital.
During the Second World War he was head of the medical section of the National Research Council of Canada.In 1941 he died victim of a plane crash in Newfoundland.

     Willard S. Boyle 

Williard Sterling Boyle (August 19, 1924 – May 7, 2011) was a Canadian-American physicist,  pioneer in the field of laser technology and co-inventor of the charge-coupled device. On October 6, 2009, it was announced that he would share the 2009 Nobel Prize in Physics for "the invention of an imaging semiconductor circuit—the CCD sensor, which has become an electronic eye in almost all areas of photography".
After receiving his doctorate, Boyle spent one year at Canada's Radiation Lab and two years teaching physics at the Royal Military College of Canada. In 1953 Boyle joined Bell Labswhere he invented the first continuously operating ruby laser with Don Nelson in 1962, and was named on the first patent for a semiconductor injection laser. He was made director of Space Science and Exploratory Studies at the Bell Labs subsidiary Bellcomm in 1962, providing support for the Apollo space program and helping to select lunar landing sites. He returned to Bell Labs in 1964, working on the development of integrated circuits.
In 1969, Boyle and George E. Smith invented the charge-coupled device (CCD), for which they have jointly received the Franklin Institute's Stuart Ballantine Medal in 1973, the 1974 IEEE Morris N. Liebmann Memorial Award, the 2006 Charles Stark Draper Prize, and the 2009 Nobel Prize in Physics. However, Eugene Gordon and Mike Tompsett, two now-retired colleagues from Bell labs, claim that its application to photography was not invented by Boyle. The CCD allowed NASA to send clear pictures to Earth back from space. It is also the technology that powers many digital cameras today. Smith said of their invention: "After making the first couple of imaging devices, we knew for certain that chemistry photography was dead." Boyle was Executive Director of Research for Bell Labs from 1975 until his retirement in 1979. In retirement, he split his time between Halifax and Wallace, Nova Scotia. In Wallace, he helped launch an art gallery with his wife Betty, a landscape artist. He was married to Betty since 1947, and had four children, 10 grandchildren and one great-grandchild. He was appointed a Companion of the Order of Canada — the award's highest level — on June 30, 2010. In his later years, Boyle suffered from kidney disease, and due to complications from this disease, died in a hospital in Wallace on May 7, 2011.

     Gerhard Heinrich Friedrich Otto Julius Herzberg.

Gerhard Heinrich Friedrich Otto Julius Herzberg, PC CC FRSC FRS (December 25, 1904 – March 3, 1999) was a German-Canadian pioneering physicist and physical chemist, who won the Nobel Prize for Chemistry in 1971, "for his contributions to the knowledge of electronic structure and geometry of molecules, particularly free radicals". Herzberg's main work concerned atomic and molecular spectroscopy. He is well known for using these techniques that determine the structures of diatomic and polyatomic molecules, including free radicals which are difficult to investigate in any other way, and for the chemical analysis of astronomical objects. Herzberg served as Chancellor of Carleton University in Ottawa, Canada from 1973 to 1980.
Initially, Herzberg considered a career in astronomy, but his application to the Hamburg Observatory was returned advising him not to pursue a career in the field without private financial support.  After completing high school, Herzberg continued his education at Darmstadt University of Technology with the help of a private scholarship. Herzberg completed his Dr.-Ing. degree under Hans Rau in 1928.
Herzberg's most significant award was the 1971 Nobel Prize in Chemistry, which he was awarded "for his contributions to the knowledge of electronic structure and geometry of molecules, particularly free radicals". During the presentation speech, it was noted that at the time of the award, Herzberg was "generally considered to be the world's foremost molecular spectroscopist."
Herzberg was honoured with memberships or fellowships by a very large number of scientific societies, received many awards and honorary degrees in different countries.The NSERC Gerhard Herzberg Canada Gold Medal for Science and Engineering, Canada's highest research award, was named in his honour in 2000. The Canadian Association of Physicists also has an annual award named in his honour. The Herzberg Institute of Astrophysics is named for him. He was made a member of the International Academy of Quantum Molecular Science. Asteroid 3316 Herzberg is named after him. In 1964 he was awarded the Frederic Ives Medal by the OSA. At Carleton University, there is a building named after him that belongs to the Physics and Mathematics/Statistics Departments, Herzberg Laboratories.
