Person

Max Frei

Max Frei-Sulzer (1913-1983) was a Swiss criminalist and palynologist, founder of the scientific section of the Zürich cantonal police, who in the 1970s collected and analyzed pollen samples from the Shroud of Turin using adhesive-tape lifts. He identified pollen from dozens of plant species, a substantial fraction of which are native to the eastern Mediterranean, particularly Judea, Anatolia, and the area around Constantinople, supporting a provenance trail consistent with the Mandylion thesis (Jerusalem → Edessa → Constantinople → western Europe).

Significance

Frei's botanical analysis is one of the load-bearing planks in the historical-provenance case for the Shroud's pre-14th-century existence in the Levant. His work has been criticized on methodological grounds, adhesive-tape sampling is contamination-prone, and species-level identification from single pollen grains is contested, and his earlier non-Shroud work (most famously, his initial authentication of the later-discredited "Hitler diaries") has been used to undermine his credibility. Defenders of the Shroud note that Frei's pollen samples were independently re-examined and that the Judean species identifications survive the methodology critiques.
