William Smith (March 23, 1769 - August 28, 1839) was an Englishgeologist. Smith is credited with creating the first nationwide geologic map and is known as the "Father of English Geology". However, recognition was slow in coming. His work was plagarized, he was financially ruined and spent time in debtor's prison. The genteel practitioners of the new science of geology and founders of the geological societies snubbed the low-born Smith. It was only much later in Smith's life that he received recognition for his accomplishments. In January 1831 the Geological Society of London conferred on Smith the first Wollaston medal. It was on this occasion that Adam Sedgwick referred to Smith as "the Father of English Geology".
Father of modern toxicology: Paracelsus said, "dose determines the poison". Paracelsus, who lived in the 15th century was the first person to explain the dose response relationship of toxic substances.
Mathieu Orfila is considered to be the father of toxicology, having given the subject its first formal treatment in 1813 in his Trait des poisons, also called Toxicologie generate.
Euclid of Alexandria (Greek: Eukleides) (circa 365 BC – 275 BC) was a Greekmathematician, now known as "the father of geometry". His most famous work is Elements, widely considered to be history's most successful textbook. Within it, the properties of geometrical objects and integers are deduced from a small set of axioms, thereby anticipating (and partly inspiring) the axiomatic method of modern mathematics. Although many of the results in Elements originated with earlier mathematicians, one of Euclid's major accomplishments was to present them in a single, logically coherent framework. In addition to providing some missing proofs, Euclid's text also includes sections on number theory and three-dimensional geometry. The geometrical system described in Elements was long known simply as "the" geometry. Today, however, it is often referred to as Euclidean geometry to distinguish it from other so-called non-Euclidean geometries which developed in the 19th century. These new geometries grew out of more than two millennia of investigation into Euclid's fifth postulate, one of the most-studied axioms in all of mathematics.
In 1939, Dr. Frank W. Cyr of New York, who became known as The Father of the Yellow School Bus, hosted a 7 day long national conference of industry and school leaders which established 44 important safety standards and the yellow color for school buses all across the United States.
Gabriel Bell (DS9, "Past Tense") (April 24, 1987 - September 3, 2024) During a 2024 revolt in San Francisco where federal employees were held hostage, he made sure the hostages were not harmed. In an alternate timeline, Bell was killed earlier and Benjamin Sisko stepped in to fulfill Bell's role in the pivotal historical moment. In a guidebook to Earth that Jake gave to Nog, Gabriel Bell is described as "the father of Earth's post-modernreformism," and shown with a picture of Sisko.
