Born 1958 in Frankfurt am Main, lives and works in Frankfurt am Main.

1984 first Expanded Cinema Installation at Frankfurt Feste, Alte Oper, with scratched slides and film loops.

Since „andere Orte“ („Different Places“), with 360 projected scratchings at Oktogon II., Museum Wiesbaden 1990, Nikolaus A. Nessler is exploring the esthetic of light in space and darkness. Important works were shown at „Arte Amazonas“ (Rio de Janeiro, Brasilia, Berlin, Dresden, Aachen 1992/94), DEPOT 2 (Steirischer Herbst, Graz 1993), THE VICTIM IS THE SACRIFICE (Dänemark 1995), und BEBEN/TERREMOTO, Kunsthaus Wiesbaden 2012 as experimentale installations for Luminale from 2004 to 2016.

Nesslers was called a Poetic Structuralist (by his former mentor D. Mahlow). Some works are a kind of analogy of the creation of the universe: „Energetic signals are beaming, where only cold darkness and voidness has been before. This is life.“
