Context paragraphs:
Blasphemy Act 1697: The Blasphemy Act 1697 (9 Will 3 c 35) was an Act of the Parliament of England.  It made it an offence for any person, educated in or having made profession of the Christian religion, by writing, preaching, teaching or advised speaking, to deny the Holy Trinity, to claim there is more than one god, to deny the truth of Christianity and to deny the Bible as divine authority.

Ronald Loui: Ronald Prescott Loui is an American computer scientist and philosopher identified as "Frederick" in U.S. President Barack Obama's "Dreams From My Father" memoir, the first classmate the ten-year-old Obama meets at Punahou School.  Loui appears in Obama biographies, national and international newspaper articles, in online columns, in a film documentary, on NPR and on Fox TV news.  In cartoon form, he appears as Obama's childhood sidekick in the comic biography by Jeff Mariotte.  Loui is the first friend named and quoted by Obama in his memoir.  In a radio interview, Loui explained that his brother Terrence was really the first person who welcomed Obama and his grandfather to Punahou (so the character in the memoir is a composite of two people).

Jeff Bauman: Jeff Bauman Jr. is an American author.  He lost his legs in the Boston Marathon bombing and was the subject of a famous photograph taken in the aftermath of the bombing.  The 2017 film "Stronger" is based on a memoir of the same name he co-wrote, with Jake Gyllenhaal portraying him.

Heilpraktiker: Heilpraktiker ("healing practitioner") is a naturopathic profession in Germany.  It is recognized as an alternative and complementary health care profession by German law.  A heilpraktiker does not need to have any formal education or training but must do an exam at the health authorities.  This exam used to be somewhat basic until the 1980s, at which time it was made to become much more demanding.  A candidate needs to have good knowledge of medical sciences, such as anatomy, physiology and pathology and psychiatry; a good knowledge of law regulations is also needed.  Healing practitioners often specialize in a complementary and alternative field of healthcare that could be anything from homeopathy, phytotherapy, Chinese medicine, Ayurvedic medicine, to reflexology or acupuncture.  A healing practitioner is a person who is allowed to practice as a non-medical practitioner using any unconventional therapy.  About 35000 heilpraktiker are accredited in Germany.

Graduate school: A graduate school (sometimes shortened as grad school) is a school that awards advanced academic degrees (i.e. master's and doctoral degrees) with the general requirement that students must have earned a previous undergraduate (bachelor's) degree with a high grade point average.  A distinction is typically made between graduate schools (where courses of study vary in the degree to which they provide training for a particular profession) and professional schools, which offer specialized advanced degrees in professional fields such as medicine, nursing, business, engineering, or law.  The distinction between graduate schools and professional schools is not absolute, as various professional schools offer graduate degrees (e.g., some nursing schools offer a master's degree in nursing).  Also, some graduate degrees train students for a specific profession (e.g. an MSc or a PhD in epidemiology trains a person to be an epidemiologist).

Stronger (film): Stronger is a 2017 American biographical drama film directed by David Gordon Green and written by John Pollono, based on the memoir of the same name by Jeff Bauman and Bret Witter.

Horace Ezra Bixby: Horace Ezra Bixby (May 8, 1826 - August 1, 1912) was a steamboat pilot on the Mississippi-Missouri-Ohio river system from the late 1840s until his death in 1912.  Bixby is notable in his own right for his high standing in his profession, for his technical contributions to it, and for his service in the American Civil War.  However, he is best known for having had as his "cub pilot" (that is, apprentice or trainee) the young man known to him as Sam Clemens, later to become famous under his pen name as American author Mark Twain.  Twain's descriptions of Bixby's character and pedagogic style form a good part of his memoir "Life on the Mississippi", and it was through this medium that Bixby—much to his annoyance—became well-known beyond the circles of his family, friends and profession.

Archagathus (son of Lysanias): Archagathus (Ancient Greek: Ἀρχάγαθος ), a Peloponnesian, the son of Lysanias, who settled at Rome as a practitioner of medicine around 219 BCE, and, according to Lucius Cassius Hemina, was the first person who made it a distinct profession in that city.  He was received in the first instance with great respect, he was accorded the "Jus Quiritium" -- that is, the privileges of a free native of Rome -- and a shop was bought for him at the public expense; but his practice was observed to be so severe, that he soon excited the dislike of the people at large, and produced a complete disgust to the profession generally.  In return for the favors he received from the Romans, he purged, bled, hacked, and cauterized them to such a degree, that at length they refused to tolerate such rough treatment any longer, and the commonwealth was purged of Archagathus himself.

Table talk (literature): Table talk is a literary genre, a species of memoir.  A collector (biographer, colleague, friend, etc.) records impromptu comments by some famous person (made generally at the dining table or in small get-togethers), in anticipation of their lasting value.  The precedent in classical literature was the symposium, such as the "Table Talk" of Plutarch, though this was a supposed memoir of an occasion, rather than a person.
