Gabriella Morreale de Escobar

Gabriella Morreale de Escobar(7 April 1930 – 4 December 2017) was an Italian-born Spanishchemistwho specialised in thethyroid.She and her husbandFrancisco Escobar del Reyshowed that thyroid hormones cross the placenta during pregnancy and are essential for fetal brain development. She established a nationalnewborn screeningprogram forcongenital hypothyroidismin Spain and helped to introduceiodised saltto prevent thyroid problems caused by iodine deficiency.

Biography

Morreale was born in 1930 inMilan,Italy. Her father, Eugenio Morreale, was a Sicilian biologist and diplomat, and her mother, Emilia de Castro, was a biologist and a curator for theMuseo Civico di Storia Naturale di Milano(Milan Natural History Museum).She attended schools inVienna,Austria andBaltimore,United States, before finishing theBaccalaureateinMálaga,Spain. She studied chemistry at theUniversity of Granada,earning a doctoral degree.Her doctoral thesis showed that the incidence ofendemic goitrein theAlpujarrasregion was closely linked toiodine deficiency.In 1953, she married Francisco Escobar del Rey, with whom she would collaborate for the rest of her scientific career.

Morreale and Escobar travelled toLeiden,the Netherlands, to perform post-doctoral research onthyroid hormonemetabolism usingradioisotopesofiodine.They returned to Spain in 1958 and began working in theSpanish National Research Council.From 1963 to 1975, she led the thyroid studies division of the Gregorio Marañón Health Research Institute in Madrid.In 1974, Morreale and Escobar became employed by theAutonomous University of Madrid,where they co-founded the Instituto de Investigaciones Biomedicas. Morreale's early research demonstrated throughanimal studiesthatthyroxine(T4) is converted totriiodothyronine(T3),and she developed sensitiveradioimmunoassaysfor the detection of T3 and T4.She showed that, in pregnant women, maternal thyroid hormones are transferred via theplacentato the fetus and maternal-fetal transfer of T4 is important for fetal brain development.She implemented a nationalnewborn screeningprogram forcongenital hypothyroidismin Spain and her research led to the introduction ofiodised saltin Spain to prevent endemic goitre caused by iodine deficiency.

Morreale was a co-founder of the European Thyroid Association and served as its president from 1978 to 1980.She was awarded an honorary doctorate in medicine from theUniversity of Alcaláin 2001and became an honorary member of theEuropean Society of Endocrinologyin 2008.She died on 4 December 2017 at 87 years old.
