Henk Spekreijse suffered a fatal heart attack in Amsterdam on the 20th

>From 1991 to 2004 Henk was Chairman of the board and Editor in Chief of the
journal " Vision Research".Under his guidance the journal flourished and
expanded to 28 issues per year. He worked with Elsevier to introduce and
fund the pre - ARVO special symposia, and initiated the publication of
special issues of the journal which bring together scientists from different
disciplines to discuss questions of high interest in vision research. Henk
was closely involved in the integration of resources and expertise in
Ophthalmology Departments throughout the Netherlands , and was Director of
Research at the Netherlands Interuniversity Eye Institute.

Henk is internationally recognised as one of the outstanding vision
scientists of his time.

In the mid - 1960s Henk burst in to top level research as a pioneer in the
application of nonlinear systems analysis to electrophysiology. 

With his students and colleagues he adopted this approach in studies of
retinal and cortical single - unit electrophysiology in monkeys, and slow -
wave electrophysiology in human and monkey cortex and in fish and human
retinas. More recently the work of his laboratory, combining psychophysics
with electrophysiology in studies on alert behaving monkeys produced
important discoveries on object - based attention.His innovative thinking
and advanced experimental techniques immediately attracted wide attention in
the mid - 1960s and continued to characterise his work throughout his life.
Henk was supervisor of electrophysiological research at the Amsterdam
University Eye Clinic. 

The medical research of that group is, perhaps, best known for the
documentation of the normal development of visual evoked potentials from the
age of a few weeks up to 10 years that provided physicians with a baseline
for developmental disorders.

In 1985 Henk was elected Fellow of the Netherlands Royal Academy of Arts and

An obituary will be published in " Vision Research".
