Biography of Agnete Parving


Agnete Parving was born in 1943 and graduated in medicine from the University of Copenhagen in 1969. In 1981 she became an ENT specialist, and in 1985 she obtained her Doctorate. Agnete started her research career and had most of her clinical training in audiological medicine at the audiological department at Copenhagen University Hospitals.

In 1983 Agnete became head of Department of audiology at Copenhagen University Hospital Bispebjerg, and she was in 1994 appointed professor in clinical audiology. In 2003 Agnete chose to leave the clinical work to hold a position as senior research associate.

Agnete has held honorary positions in national and international audiological associations. Besides being honorary member of IAPA, Agnete is honorary member of la Società Italiana di Audiologia e Foniatria and the Polish Audiological and Phoniatric society.

From 2002-2005 Agnete was vice-President in IAPA, but during a meeting in Lyon 2005 Agnete declared her wish to step down as IAPA vice-president. Agnete had retired from her position as the director of the Department of Audiological Medicine, Bispebjerg Hospital in Copenhagen two years earlier and although she was very much active as a senior researcher and as a professor of clinical audiology she argued that the leadership of the IAPA should be reserved for those active in the clinical field.

The General Assembly unanimously accepted the proposition of the IAPA president, Jose Barajas, to elect Agnete Parving as an Honorary Life Member of IAPA.

Agnete is well known to us all and she is undeniably the Grand Lady of Scandinavian audiology. She has been an active IAPA member almost since the beginning and an EC member for many years. We, the members of IAPA, all thank Agnete for her efforts in promoting Audiologcial Medicine all over the world and we welcome her continuing efforts as an active IAPA Honorary Member and the ambassador of our speciality for life.

Agnete’s main areas of research are: genetic causes of hearing loss and hearing and loss of hearing in children.

Biography of Wolf-Dieter Keidel


Wolf-Dieter Keidel was a German MD and Physiologist.

Wolf-Dieter Keidel (born December 14, 1917 in Gaimersheim; † January 17, 2011 in Bayreuth), was a German physician and physiologist sense.

Life and Work

Keidel studied medicine at the Universities of Würzburg, Vienna and Munich. 1945-47 he was an assistant at the Physical-Medical Laboratory of the University of Erlangen. He then went to the local Physiological Institute. In 1949 he was habilitated and in 1956 appointed as Professor. In 1961 he was appointed Chair of Physiology and director of the Physiological Institute newly renamed as Friedrich-Alexander-University Erlangen-Nuremberg. 1965 Keidel became director of the Institute of Physiology and Biocybernetics of the University, a position he held until his retirement in 1986.

In 1963 Keidel was the founding president of the German Society for Cybernetics.

Sonography: After the ultrasound was introduced in the late 1940s at the same time in several medical specialties, in 1950 Keidel was first to used echocardiografy, a cornerstone of today’s cardiac diagnostics.

Hearing: Keidels main work builds on the results of Georg von Békésy on hearing. In 1961 he showed how the objective audiometry is correlated with the auditory evoked potentials from the EEG resulting from presented sound pressure. Using the method, it is possible also in neonates and infants to detect a hearing impairment. This method was further developed into Brainstem Evoked Response Audiometry (BERA).

Textbook: Keidel was editor and co-author of the concise textbook of physiology, published in six editions 1967-1985 and translated into several languages. It was the last major German-speaking physiology textbook for medical students, that is modeled on the physico-chemical principles of physiology. Diagrams from then current technical publications were integrated into the work and so shortened the transition from learning to a research student.

Biography of Gunnar Lidén


Professor Lidén was born in 1918. His medical studies took place in Stockholm during the 1940s. From 1945-1950 he worked at the Karolinska hospital in the department of Otorhinolaryngology. After the Second World War, during the 1950s, audiology was established as a speciality. Professor Lidén realised very early the need for audiological rehabilitation and undertook special training in audiology, being awarded a PhD in 1954 with a thesis on implementing Swedish speech audiometry.

In 1954 he moved to the Sahlgrenska hospital, Gothenburg were he started the Department of audiology. Gunnar Lidén was employed as Head of the department until his retirement in 1983. He became Professor of audiology in 1977.

Gunnar Lidén was one of the most important researchers in Swedish audiology. He had a major impact on the development of audiological rehabilitation, not only in Gothenburg but throughout Sweden. His thesis on speech audiometry was particularly important, and 50 years later remains a very important tool in audiological diagnostics. His researches also covered impedance audiometry.

During his professional career, in addition to his research, Gunnar Lidén also performed extensive middle ear surgery. In 1979 he started a two-year academic education for audiologists which today is a three-year bachelor programme.

Over his professional career Gunnar Lidén wrote several books on audiology as well as numerous scientific reports. His enormous working capacity and positivism resulted in a large and multidisciplinary department of audiology at Sahlgrenska University hospital.

We, present and former co-workers at the Department of audiology Sahlgrenska University hospital, express our gratitude to Gunnar for all his achievements in audiology.

Biography of Wolfhart Niemeyer


Wolf Niemeyer, a founder and first President of Association of Physicians in Audiology (IAPA) died in October 2010 at the age of 87 years.

Wolfhart Niemeyer was born in Lüneburg, Germany in 1923. Soon after he had graduated from high school, he became a soldier in the Medical Corps, where he remained from 1940 to 1945, and was wounded three times while saving injured comrades.

Already during his medical studies in Mainz, which he financed by working as a portrait painter, coalman, and as an assistant to dog racers, he had become interested in audiology. He graduated with a thesis entitled ‘Perception of high-frequency supersonic sounds’.

At the University hospital in Marburg, he trained as a surgical ENT specialist, while conducting scientific studies in audiology. These studies were concerned with the diagnosis and pathology of auditory sentence discrimination and resulted in his dissertation. The Marburger Satztest became a key test in hearing aid fitting.

In 1970 he was nominated ‘Extraordinarius’ and became the independent head of the Audiology Department. This created a sensation in Germany, because audiology was always a subordinate section, an appendix, of the general ENT department.

Wolf Niemeyer, as he was called by his friends, became the most world-renowned German audiologist. This was not only because of his scientific research that had resulted in many publications, books and monographs, but also because of his countless lectures in Europe, USA, Mexico and Japan.

He was an active member of, and frequently chairman of, many ENT and audiological committees and wrote thousands of medico-legal reports. He received many awards, including the Bundesverdienstkreuz and the Aram Glorig reward.

To the end of his life, despite a long and severe illness, he was engaged in professional politics.

Throughout his life, Wolf Niemeyer had a major aim, that the head of an audiological department should be a medical doctor, preferably with an ENT training. His efforts have not been realized to date, and he has even been regarded as persona non grata in Germany. Because of this, Wolf Niemeyer contacted like-minded medical colleagues in other countries, and, together with Ole Bentzen, Ronald Hinchcliffe and Dai Stephens founded IAPA in 1980. He organized the first meeting of IAPA in Wiesbaden in November 1980 and was elected as the first President of the Association (1980–1985). He later became an Honorary Life Member.

Many members of the IAPA and his friends, including myself, will miss Wolf as a loving friend, and will remember his sense of humour and the social gatherings held with him. He was a highly intelligent colleague with great knowledge but also great warmth. Our thoughts and condolences go to his wife, who cared for him unselfishly in his final years.
