grew, and the ICTH began to consider expanding the scope of its mission. The
number of scientists who wanted to attend its meetings was increasing each year,
but because of its small size, the Committee could only accommodate a few
Planning for Expansion
the better part of the 1960s, members of the ICTH clarified and planned the
mission, structure, function and leadership of a larger organization. They
envisioned a society that would be open to all researchers, clinicians,
educators and students working in the many interrelated fields of thrombosis, haemostasis
and vascular biology.
ICTH had focused primarily on blood coagulation and hemorrhagic disorders; the
new organization would expand that focus to include the emerging areas of
platelet function and regulation, the mechanisms of thrombosis, fibrinolysis
and thrombolysis, and the urgent problems of thromboembolic disorders.
Birth of a New Society
In 1969, at the ICTH’s 15th Annual Meeting in
Bath, UK, its members finally came to a vote—unanimously approving the creation
of the International Society on Thrombosis
and Haemostasis (ISTH).
The Society chose Fritz Koller of Switzerland as its
President and Sol Sherry of the USA as Chairman of the newly-formed ISTH Council. Almost 200
scientists joined the Society that year, and of those, 37 are still active members.
Today, the ISTH’s impact and contributions to the understanding,
prevention, diagnosis and treatment of thrombotic and bleeding disorders span six
continents. With more than 3,800 members in over 94 countries, we are now the
leading thrombosis- and haemostasis-related professional organization in the
