Girolamo Fabrici (1537-1619)
Girolamo Fabrici, known as Hieronymus Fabricius in Latin, was given the surname Aquapendente from the city where he was born, near Orvieto, Italy. Born in 1533, Fabrici was the eldest son of a respected noble family, whose coat of arms appears as an illustration in the title page of Fabrici's book on embryology, De formato foetu. Little is known of Fabrici's parents. His father is recorded as Fabricio, and Fabrici is said to have been named for his paternal grandfather.

De Formato Foetu (c. 1600), by Girolamo Fabrici
The embryological treatise De formato foetu (The Formed Fetus) was written by anatomist and embryologist Girolamo Fabrici. There is no conclusive evidence regarding the first date of publication and what is listed on many copies ranges from 1600-1620, with speculation that the dates were altered by hand. Most forms of the book are dated 1600 and were issued by Franciscus Bolzetta who sold many copies in Venice and whose name appears on the engraved title-page. There is also verification of the book being printed in Padua by Laurentius Pasquatus in 1604.

De Formatione Ovi et Pulli (1621), by Girolamo Fabrici
The embryological treatise De formatione ovi et pulli (On the Formation of the Egg and of the Chick) was written by anatomist and embryologist Girolamo Fabrici and published in Padua posthumously in 1621. The book was edited by Joahannes Prevotius and is separated into two parts that describe Fabrici's observations and assumptions on embryology and combine the traditional knowledge of his predecessors with his own first-hand anatomical observations.

Pope Pius IX (1792-1878)
Pope Pius IX, born Giovanni Maria Mastai-Ferretti, marked his contribution to the abortion debate by removing the distinction between an "animated" and "unanimated" fetus from Catholic doctrine, and established the edict that a human should be protected starting from the moment of conception onward. This proclamation made abortion at any time of gestation punishable by excommunication. Pope Pius IX's decision became Canon Law of the Catholic Church.

Methylmercury and Human Embryonic Development
Methylmercury (MeHg) is an organic form of mercury that can damage the developing brains of human fetuses. Women who consume methylmercury during pregnancy can bear children who have neurological issues because methylmercury has toxic effects on the nervous system during embryonic development. During the third week of gestation, the human nervous system begins to form in the embryo. During this gestational period, the embryo's nervous system is particularly susceptible to the influence of neurotoxins like methylmercury that can result in abnormalities.
