Definition
Franz Hillenkamp (born 7 October 1936) is a German physicist and professor emeritus renowned for his pioneering contributions to matrix‑assisted laser desorption/ionization (MALDI) mass spectrometry, a technique that enabled the analysis of large biomolecules.
Overview
Hillenkamp studied physics at the University of Bonn, completing his diploma in 1962 and receiving a doctorate (Dr. rer. nat.) in 1968 under the supervision of Heinrich K. H. von Kern. He subsequently held research positions at the Max Planck Institute for Nuclear Physics in Heidelberg and later at the University of Münster, where he was appointed professor of applied physics in 1979.
In the early 1980s, Hillenkamp collaborated with chemist Michael Karas to develop MALDI. Their work, first reported in 1985, demonstrated that a short‑wave ultraviolet laser could desorb and ionize large biomolecules from a suitable organic matrix without extensive fragmentation. This breakthrough facilitated the mass‑spectrometric analysis of proteins, polymers, and other high‑molecular‑weight compounds, transforming analytical chemistry, proteomics, and clinical diagnostics.
Hillenkamp continued to refine MALDI instrumentation and methodology, contributing to the commercialization of MALDI‑TOF (time‑of‑flight) mass spectrometers. He retired from active research in 2004 but remains an influential figure in the mass‑spectrometry community.
Etymology/Origin
The surname “Hillenkamp” is of German origin. It is a toponymic name derived from a place name, likely referring to a “hill” (German Hügel or Hille) combined with “Kamp,” an old German word for a field or enclosed tract of land. Thus, Hillenkamp can be interpreted as “field on a hill” or “settlement near a hill.”
