Prof. Toni Lindl passed away on May 12, 2022 in Munich. He studied chemistry and biology at the Technical University Munich and University of Freiburg and later worked at the universities of Konstanz and Bonn. Toni Lindl established the Institut für Angewandte Zellkultur – I-A-Z (Institute for Applied Cell Culture) in Munich in 1981 and became a professor at the University of Applied Sciences Weihenstephan in 1990. In 1987 Toni Lindl published the standard textbook Zell- und Gewebekultur (Cell and Tissue Culture), which is currently in its 8th edition. Alternatives to animal experimentation were a central interest of Toni Lindl’s on which he published important contributions, also in ALTEX. We will miss Prof. Toni Lindl and continue to honor his contributions to cell and tissue culture.
