Phaedon Fessas

Phaedon Fessas (1922-2015) was a Greek Professor of Medicine at the Medical School of Athens University. He was Director of the 1st Department of Internal Medicine at the Laikon Hospital in Athens (1969-1989), where he established a very strong Hematology Division, his particular subspecialty. Professor Fessas was a clinician, teacher and researcher. His main research interest was thalassemia.

He graduated from the Experimental School of the University of Athens in 1939.

He started his studies at the Medical School of the University of Athens in 1939 and due to the War he graduated in 1947.

In the Greek-Italian War he served as a stretcher bearer ιn the Red Cross, in the blood donation service.

During the Occupation he participated in the National Resistance by contributing in the publication of the "Radio Bulletin" and the newspaper "Eleftheria". He was arrested and imprisoned twice, by the Italians in 1942 and by the Germans in 1944.

He began working at the 2nd Internal Medicine Department of the University of Athens in January 1948 as an in-house assistant and immediately afterwards served as an army doctor until 1951.

From 1952 to 1954 he completed his postgraduate studies with a Fulbright Scholarship at the Utah University Medical School, next to Professor M.M. Wintrobe.

Returning to Greece, in 1955 he was named Doctor of Medicine of the Athens Medical School.

From 1955 to 1957 he worked as a Registrar in the Second Medical Department under Professor Arkagathos Guttas. There he began his research on pathological hemoglobins, types of thalassemia and the development of methods for the diagnosis and investigation of hereditary anemias.

In 1957 he took over the direction of the Blood Donation Service of the Alexandra Maternity Hospital and the organization of the Hematology Laboratory of the Department of Therapeutics, under Professor Vasilios Malamos.

In parallel with the clinical and laboratory monitoring of internal patients, the care of patients suffering from thalassemia, the teaching and education of students and specialists, he began his research work that made him internationally known.

His special interest were the hemoglobinopathies, with a major focus on thalassemia. He studied and described the pathological physiology of these disease syndromes and he was the first to describe inclusions in erythroblasts and red cells in β-thalassemia, which were named Fessas bodies and pointed out the importance of embryonic hemoglobin. He also studied the incidence and distribution of thalassemia in the Greek population, which ultimately led to the design of a very successful diagnosis and prevention program. He has also dealt with the ethical issues that arise from the development of science in these areas.

In 1965 he was elected Lecturer of the University of Athens and the subject of his dissertation was "The derangement of hemoglobin synthesis in thalassemia". Among his numerous contributions to the field of thalassemia, some of whom are cited in Bibliography below, are two seminal papers in the journals Nature and Science and a Book on Radiology of Thalassemia.

In 1969 he was elected Professor of Internal Medicine at the Medical School of the University of Athens and took over the direction of the 1st Department of Internal Medicine at the Laikon Hospital.

During this 20 years as Professor, the 1st Department of Internal Medicine became an example for the training of new doctors in Clinical Medicine and especially in Clinical Hematology. Many generations of Greek Hematologists and Internists have been taught by Professor Fessas and several of his students became themselves Professors of Medicine or Hematology or Directors of big Hematology Departments in Greece and abroad.

In 1987 he was elected President and in 1988 Dean of the School of Health Sciences.

In 1989 he left the University and was named Professor Emeritus.

He was among the founding members and one of the early Presidents of the Hellenic Society of Hematology.

With his collaborators he established the Greek Centre for Diagnosis and Prevention of Thalassemia, which had resulted in a very significant reduction of births of infants with thalassemia in Greece.

After his retirement he remained close to the University and the Thalassemia Center offering his services in every way. He managed to realize his dream of organizing and operating the Library of Health Sciences in 1997 and was the President of this Library until 2000.

He received many awards and honorary titles and served as Dean of the School of Medicine of the Athens University.

The Hellenic Society of Hematology established an annual "Phaedon Fessas" award to be given at the Annual Meeting of the Society to the best scientific presentation.
