Thomas Hunt Morgan (September 25, 1866 – December 4, 1945) was an American geneticist and embryologist. Morgan received his PhD from Johns Hopkins University in 1890 and researched embryology during his tenure at Bryn Mawr. Following the rediscovery of Mendelian inheritance in 1900, Morgan’s research moved to the study of mutation in the fruit fly Drosophila melanogaster. In his famous Fly Room at Columbia University Morgan was able to demonstrate that genes are carried on chromosomes and are the mechanical basis of heredity. These discoveries formed the basis of the modern science of genetics. When he was awarded the Nobel Prize in Physiology or Medicine in 1933 he was the first person awarded the Prize in genetics, for his discoveries concerning the role played by the chromosome in heredity.

John Marshall (September 24, 1755 – July 6, 1835) was the Chief Justice of the United States (1801–35) whose court opinions helped lay the basis for American constitutional law and made the Supreme Court of the United States a coequal branch of government along with the legislative and executive branches. Previously, Marshall had been a leader of the Federalist Party in Virginia and served in the United States House of Representatives from 1799 to 1800. He was Secretary of State under President John Adams from 1800 to 1801.

The longest-serving Chief Justice of the United States, Marshall dominated the Court for over three decades and played a significant role in the development of the American legal system.

Michael Faraday – English scientist who established the foundations of electical theory.

Michael Faraday (22 September 1791 – 25 August 1867) was an English chemist and physicist (or natural philosopher, in the terminology of the time) who contributed to the fields of electromagnetism and electrochemistry.

Faraday studied the magnetic field around a conductor carrying a DC electric current, and established the basis for the electromagnetic field concept in physics. He discovered electromagnetic induction, diamagnetism, and laws of electrolysis. He established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.  His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became viable for use in technology.

John Loudon McAdam – Father of paved roads

Deutsch: John Loudon McAdam

John Loudon McAdam (21 September 1756 – 26 November 1836) was a Scottish engineer and road-builder. He invented a new process, “macadamisation“, for building roads with a smooth hard surface that would be more durable and less muddy than soil-based tracks.

Modern road construction still reflects McAdam’s influence. Of subsequent improvements, the most significant was the introduction of tar (originally coal tar) to bind the road surface’s stones together – “tarmac” (for Tar Macadam) – followed later by the use of hot-laid tarred aggregate or tar-sprayed chippings to create better road metalling. More recently, oil-based asphalt laid on reinforced concrete has become a major road surface, but its use of granite or limestone chippings still recalls McAdam’s innovation.

Samuel Johnson (18 September 1709 – 13 December 1784), often referred to as Dr. Johnson, was an English author. Beginning as a Grub Street journalist, he made lasting contributions to English literature as a poet, essayist, moralist, novelist, literary critic, biographer, editor and lexicographer. Johnson was a devout Anglican and political conservative, and has been described as “arguably the most distinguished man of letters in English history”.  He is also the subject of “the most famous single work of biographical art in the whole of literature”: James Boswell‘s Life of Samuel Johnson.

Margaret Higgins Sanger Slee (September 14, 1879 – September 6, 1966) was an American birth control activist and the founder of the American Birth Control League (which eventually became Planned Parenthood). Although she was initially met with opposition, Sanger gradually won some support for getting women access to contraception. In her drive to promote contraception and negative eugenics, Sanger remains a controversial figure.
