In Memoriam for Dr. Thomas Knacker
Dr. Thomas Knacker
On October 30, 2011 we lost Dr. Thomas Knacker, a much valued colleague, research partner and friend. We miss his congenial and gentle nature, his quiet sense of humour and the diplomatic way in which he worked with people. We highly regret the loss of an internationally honoured ecotoxicologist. The colleagues and friends that wish to express their sorrow in this letter of remembrance include individuals from a variety of organizations and academic institutions in Europe and abroad.
SETAC-Europe, the Federal Environment Agency and the Federal Institute of Hydrology also want to recognize as institutions the lifelong commitment of Thomas to ecotoxicology and to express regret at his passing too soon in life. The Board of the environmental chemistry and toxicology subgroup within the GDCh (Gesellschaft Deutscher Chemiker) is deeply saddened about Thomas’ sudden and unexpected death. He served for two years as our colleague on the board, and enriched our work through his outstanding expertise in environmental risk assessment of chemicals. His thoughtful, friendly and reliable work in the Executive Board will be sorely missed.
The interdisciplinary DWA-GDCh group “anthropogenic micropollutants in the urban water cycle” will always remember the contribution that Thomas made to open our eyes to ecotoxicological views. His profound expertise made the work group much more worthy. Thomas was a member for more than 10 years in our group and we are very thankful and proud to have worked with him. We will miss him very much as a good friend and an excellent scientist.
Thomas was one of the founding members of the highly successful ecotoxicology consulting and contract research company for almost 20 years, ECT Oekotoxikologie GmbH, based in Flörsheim, Germany. Through his leadership with the company, he took an active role in ecotoxicology research in Europe, including his role as the Principal Investigator with “ERAPharm”, a large EU 6th Framework Project that involved researchers from 8 different countries.
We all got to know Thomas as a generous and likeable person. By enthusiastic and inspirational discussions, he encouraged all of us to see new possibilities in ecotoxicological research. He was always very open-minded and ready to share knowledge, and especially enjoyed taking mentorship roles with young scientists. On many occasions he gave talks to students and impressed the audience as a role model for young scientists interested in applied ecotoxicology.
We will always remember Thomas as a skilled scientist with a high international reputation, as a valued colleague, a good friend and as a sincerely engaged mentor. We feel the loss when regarding the empty place that he has left behind among the ranks of ecotoxicologists and among his friends. Our condolences and thoughts go out to his wife, Margitta, his daughter Katharina and to his family.
