Max Frei-Sulzer (1913–1983) is a Swiss criminalist who has been into forensic studies particularly in tape life method in collecting evidence. He also got into handwriting analysis and microbiological sampling techniques. He was notable for the famous identification cases of Hitler's handwriting and the Shroud of Turin.
He worked for the authenticity of the Shroud of Turin using the tape lift method. Basically what it does is to preserve the configuration of the material in a particular object so as to interfere with the subsequent chemical analysis. After two years of analysis and comparison of the pollen grains from the times of Christ in Palestine with the current pollen grains growing around the middle east, he concluded that the veracity of the Shroud of Turin. However, some scientist disagreed with his analysis with their separate analysis.
He also worked on the handwriting of Hitler diaries and declared the authenticity of some of the works. However, supporting details proved that the diaries are not real. It was assumed that Frei-Sulzer used the forged writings that brought up wrong conclusions.
These two debatable findings led to stable proofs of the identities of the cases.
Max Frei-Sulzer made many contributions including finding a Swiss criminalistic labroatory. He also developed the method where a tape is put on a surface and evidence can be found once it is pulled away. Some of his assumptions turned out to be fake so he was doubted.
Max Frei-Sulzer helped to contribute a lot in the field of forensic science. For example, for trace evidence, he helped to develop the method of tape life and also founded Switzerland's very first criminalistics laboratory.
