Erich Sackmann

Erich Sackmann (Born on 26th November 1934 in Baierbronn, Germany) is an eminent Experimental Physicist.

He studied in the University of Stuttgart (Universität Stuttgart) and finished his degree in 1964. After working in Bell Telephone Laboratories in Murray Hill, N.J., USA (Bell Telephone Laboratories) and in Max-Planck-Institut für Biophysikalische Chemie [http://www.mpibpc.mpg.de/english/start/index.php] in Göttingen, in 1974 he became a Professor in Universität Ulm (Universität Ulm). 1980 he shifted to the Technical University of Munich (TU München) as the head of the Biophysics chair - E22. To this day, remains there as an emiratus professor.

Prof. Sackmann dedicated a lifetime of research towards probing the living cell with tools of physics, long before biophysics was the mode of the day. Considered by many the father of biophysics in Europe, he pioneered, along with others, the idea of a “bottom up” approach towards understanding the cell – starting from relatively simple systems like lipid bilayers, giant vesicles and actin in solution and going towards more and more complex systems to reach eventually an understanding at the level of the entire cell.

More than 200 publications and several books [http://dispatch.opac.ddb.de/DB=4.1/REL?PPN=107150948 Literatur von und über Erich Sackmann] testify to his contributions to soft matter and biophysics. His early work was mainly on lyotropic liquid crystals and lipid membranes. Later, along with his students he laid the foundations of our current understanding of membrane adhesion. Over the years his team developed and improved the technique of reflection interference contrast microscopy (RICM [ [http://www.jcb.org/cgi/reprint/20/2/199] ] [J. Radler, and E. Sackmann, “Imaging optical thicknesses and separation distances of phospholipid vesicles at solid surfaces,” J.Phys-II 3, 727-748 (1993)] – a powerful tool to probe adhesion of membranes and thin films. Collaborations with theoreticians like Reinhard Lipowsky, Udo Seifert and Robijn Bruinsma have led to seminal works on adhesion of cell mimetic giant vesicles (also called liposomes).

Another of his interests is the cytoskeleton and its dynamics. To study cytoskeletal dynamics his team developed magnetic tweezers capable of exerting very small pulling forces. He has contributed to our understanding of the dynamics of single actin filaments, actin networks as well as intact living cells.

His research interests include: physics of self assembly and function of artificial and biological membranes, viscoelastic microscopy of cells, physics of the actin based cytoskeleton: micro-rheology of macromolecular networks, applications of solid-supported lipid-protein membranes, ultrathin hydrated polymer layers and polymer/membrane composite films and neutron Reflectivity as a new tool to study the self assembly of membrane associated proteins.

Along with Reinhard Lipowsky, he has authored "the Structure and Dynamics of Membranes".

In recognition of his research work, in 2006 he was awarded the Stern-Gerlach-Medal (Stern-Gerlach-Medaille) by the Deutsche Physikalische Gesellschaft (DPG, German Physical Society).
