Mother Teresa (1910-1997)
Mother Teresa, a Roman Catholic nun known for her charitable work and attention to the poor, was born 26 August 1910. The youngest child of Albanian parents Nikola and Drane Bojaxhiu, she was christened Agnes Gonxha Bojaxhiu and spent her early life in the place of her birth, present-day Skopje, in the Republic of Macedonia. In addition to her unwavering devotion to serve the sick and the poor, Mother Teresa firmly defended traditional Catholic teachings on more controversial issues, such as contraception and abortion.

Pope Gregory XIV (1535-1591)
Pope Gregory XIV, born Nicolo Sfondrati, reversed the bull of Pope Sixtus V, Effraenatum, under which an abortion at any time of gestation can be punished by excommunication. He supported the Aristotelian distinction between an "animated" and "unanimated" fetus, making abortion of an unanimated fetus punishable by lesser means. This decision contributed to the historical debates within the Roman Catholic Church on when a fetus has a soul, and when abortion was punishable by excommunication.

Pope Sixtus V (1520-1590)
Known for dropping a long-held distinction in the Catholic Church between the animated and unanimated fetus, Felice Peretti was born in Grottamare, Italy, in 1521, son of a Dalmatian gardener. In his early years, Peretti worked as a swineherd, but soon became involved in the local Minorite convent in Montalto, where he served as a novice at the age of twelve. He went on to study in Montalto, Ferrara, and Bologna, continuing his devotion to religious life, and in 1547 Peretti was ordained as priest in the city of Siena.

Pope Paul VI (1897-1978)
Pope Paul VI, born Giovanni Battista Enrico Antonio Maria Montini, has been crucial to the clarification of Roman Catholic views on embryos and abortion in recent history. His 1968 encyclical "Humanae Vitae" spoke to the regulation of birth through various methods of contraception and sterilization. This encyclical, a result of Church hesitancy to initiate widespread discussion of the issue in a council of the Synod of Bishops, led to much controversy in the Church but established a firm Catholic position on the issues of birth control and family planning.

Pope Innocent XI (1611-1689)
Pope Innocent XI, born Benedetto Odescalchi, made considerable contributions to the Roman Catholic approach to embryology by condemning several propositions on liberal moral theology in 1679, including two related to abortion and ensoulment. His rejection of these principles strengthened the Church's stance against abortion and for the idea of "hominization," meaning the presence of human qualities before birth.

Margaret Higgins Sanger (1879-1966)
Margaret Higgins Sanger advocated for birth control in the United States and Europe during the late nineteenth and early twentieth centuries. Although people used contraceptives prior to the twentieth century, in the US the 1873 Comstock Act made the distribution of information relating to the use of contraceptives illegal, and similar state-level Comstock laws also classified discussion and dissemination of contraceptives as illegal.

Merck & Company's Development of Gardasil
In 2006, the United States branch of Merck & Co. received FDA approval for Gardasil, a human papillomavirus, or HPV, vaccine that protects against HPV and the cervical cancer that can come with it. In 1891, George F. Merck founded the US branch of the company to distribute chemicals with high purity for use in research, in New York City, New York, and other areas nearby. HPV is a common sexually transmitted infection that can cause genital warts, regular skin warts, cervical cancer, and other cancers.

National Association for Down Syndrome (1960–)
The National Association for Down Syndrome, or NADS, is an organization that was founded in 1960 by Kathryn McGee in Chicago, Illinois, to support people with Down syndrome and their families in improving their quality of life. Originally named the Mongoloid Developmental Council, NADS is one of the oldest organizations serving people with Down syndrome and their families in the United States. According to NADS, Down syndrome is a genetic condition that occurs in one in every seven hundred ninety-two people and that causes delays in physical and intellectual development.

No-scalpel Vasectomy
No-scalpel vasectomy, or NSV or keyhole vasectomy, is a surgical method of sterilization that involves puncturing the skin of the scrotum to access the vas deferens, a tube that carries spermatozoa, or sperm, from the testes to the penis. The surgeon performing the procedure blocks the flow of sperm through the vas deferens, sterilizing the patient. NSV is a less invasive procedure, as it does not use a scalpel to make a deep cut on sensitive scrotal tissue.

Jérôme Lejeune (1926−1994)
Jérôme Lejeune was a French physician and researcher who studied genetics and developmental disorders. According to the Jérôme Lejeune Foundation, in 1958, Lejeune discovered that the existence of an extra twenty-first chromosome, a condition called Trisomy 21, causes Down Syndrome. Down Syndrome is a condition present in an individual since birth and is characterized by physical and developmental anomalies such as small ears, a short neck, heart defects, and short height as children and adults.

Johannes Holtfreter (1901-1992)
Johannes Holtfreter made important discoveries about the properties of the organizer discovered by Hans Spemann. Although he spent much time away from the lab over many years, he was a productive researcher. His colleagues noted that the time he spent away helped revitalize his ideas. He is credited with the development of a balanced salt medium to allow embryos to develop; the discovery that dead organizer tissue retains inductive abilities; and the development of specification, competence, and distribution of fate maps in the developing frog embryo.

Gail Roberta Martin (1944– )
In the twentieth and early twenty-first centuries, Gail Roberta Martin specialized in biochemistry and embryology, more specifically cellular communication and the development of organs. In 1981, she named any cell taken from inside a human embryo at the blastocyst stage an “embryonic stem cell”. During development, an embryo goes through the blastocyst stage just before it implants in the uterus. Embryonic stem cells are useful for experiments because they are self-renewing and able to develop into almost any cell type in the body.

Roy John Britten (1919-2012)
Roy John Britten studied DNA sequences in the US in the second
half of the twentieth century, and he helped discover repetitive
elements in DNA sequences. Additionally, Britten helped propose
models and concepts of gene regulatory networks. Britten studied the
organization of repetitive elements and, analyzing data from the
Human Genome Project, he found that the repetitive elements in DNA
segments do not code for proteins, enzymes, or cellular parts.
Britten hypothesized that repetitive elements helped cause cells to
