who wrote a book on investigation introduced the word criminalistics
Forensic science Handbook for Coroners, police officials, military policemen was written by the Austrian criminal jurist Hans Gross in 1893, and is generally acknowledged as the birth of the field of criminalistics. The work combined in one system fields of knowledge that had not been previously integrated, such as psychology and physical science, and which could be successfully used against crime. Gross adapted some fields to the needs of criminal investigation, such as crime scene photography. He went on to found the Institute of Criminalistics in 1912, as part of the University of Graz' Law School. This Institute was followed by many similar institutes all over the world.[52]
August Vollmer In the ensuing years, Vollmer's reputation as the "father of modern law enforcement" grew.[1] He was the first chief to require that police officers attain college degrees, and persuaded the University of California to teach criminal justice. In 1916, UC Berkeley established a criminal justice program, headed by Vollmer.[2] At Berkeley, he taught O.W. Wilson, who went on to become a professor and continued efforts to professionalize policing, by being the first to establish the first police science degree at Municipal University of Wichita (now Wichita State University).[3][4] This is often seen as the start of criminal justice as an academic field.
