Quiz — Erased: Onesimus and the Origins of American Inoculation

PART A — MULTIPLE CHOICE

1. In what year did Onesimus arrive in Boston in chains?

B) 1706.

Students should be able to identify the specific date cited in the lesson. Onesimus was purchased by Cotton Mather in 1706, well over a decade before the smallpox epidemic that would make his knowledge urgently relevant. [1]Best, Michael. "Note: Cotton Mather, Onesimus, and the Origins of Inoculation." Journal of the History of Medicine and Allied Sciences, vol. 66, no. 4, 2011.[7]Massachusetts Historical Society. Cotton Mather Papers and Diary documentation. Students who answer A, C, or D are misplacing the date.

2. What question did Cotton Mather ask Onesimus that changed history?

C) "Have you ever had smallpox?"

Students should identify the specific question that prompted Onesimus to reveal his knowledge of variolation. His answer — "yes and no" — followed by showing Mather a scar, is the pivotal moment the lesson builds around. [1]Best, Michael. "Note: Cotton Mather, Onesimus, and the Origins of Inoculation." Journal of the History of Medicine and Allied Sciences, vol. 66, no. 4, 2011. Students who answer A, B, or D are selecting questions not documented in the historical record.

3. What is variolation?

B) Introducing a small amount of virus into the body so it can learn to fight back.

Students should understand the basic mechanism: a small, controlled exposure to live smallpox virus, typically through a scratch in the skin, that allowed the body to develop immunity without the same risk of death as natural infection. [2]Mather, Cotton. An Account of the Method and Success of Inoculating the Small-Pox in Boston in New-England. London, 1722.[4]Winslow, Ola Elizabeth. A Destroying Angel: The Conquest of Smallpox in Colonial Boston. Boston: Houghton Mifflin, 1974. Students who answer A, C, or D are selecting definitions that do not match the documented practice.

4. Who was the only Boston physician who listened to Mather and tested variolation?

B) Zabdiel Boylston.

Students should be able to name the physician who acted during the 1721 epidemic when other doctors refused. Boylston's willingness to test the practice is central to the lesson's argument about trust in African medical knowledge. [3]Boylston, Zabdiel. An Historical Account of the Small-Pox Inoculated in New England. London, 1726.[4]Winslow, Ola Elizabeth. A Destroying Angel: The Conquest of Smallpox in Colonial Boston. Boston: Houghton Mifflin, 1974. Students who answer A, C, or D are naming figures associated with later or unrelated developments.

5. What did Boylston do before treating hundreds of patients with variolation?

A) He tested it on his own family first.

Students should recognize the personal risk Boylston took by testing an unproven-to-Boston practice on his own household before extending it to hundreds of others. This detail reinforces how seriously he treated the knowledge that originated with Onesimus. [3]Boylston, Zabdiel. An Historical Account of the Small-Pox Inoculated in New England. London, 1726. Students who answer B, C, or D are selecting events that did not occur in this order or at all.

6. Decades after Onesimus described variolation, what did Edward Jenner create using a similar principle?

B) The first vaccine, using cowpox.

Students should understand that Jenner's 1796 smallpox vaccine built on the same underlying principle as variolation, but used cowpox material instead of live smallpox virus, making it safer. [8]World Health Organization. "History of Smallpox Vaccination." who.int historical archive. Students who answer A, C, or D are selecting unrelated medical developments.

7. What pattern does this lesson argue is revealed by history remembering Jenner and Boylston but nearly forgetting Onesimus?

B) A pattern in which the origin of knowledge is erased while those who apply or popularize it are remembered.

Students should be able to identify the central argument of the lesson as a whole: the knowledge that saved countless lives originated with an enslaved African man, yet the historical record primarily credits the colonial physicians and European scientist who came later. [1]Best, Michael. "Note: Cotton Mather, Onesimus, and the Origins of Inoculation." Journal of the History of Medicine and Allied Sciences, vol. 66, no. 4, 2011.[8]World Health Organization. "History of Smallpox Vaccination." who.int historical archive. Students who answer A, C, or D are selecting responses that minimize or mischaracterize the documented pattern.

PART B — SHORT ANSWER KEY POINTS

Question 8. Onesimus told Cotton Mather "yes and no" when asked if he had ever had smallpox, then showed him a scar. Using details from the lesson, explain what this exchange reveals and why it mattered.

A strong answer should include:

• The specific exchange: Mather's direct question, Onesimus's ambiguous but revealing answer, and the physical proof of a scar demonstrating prior exposure and survival [1]Best, Michael. "Note: Cotton Mather, Onesimus, and the Origins of Inoculation." Journal of the History of Medicine and Allied Sciences, vol. 66, no. 4, 2011.
• What this reveals: Onesimus possessed direct, embodied evidence of a medical practice unfamiliar to colonial Boston, and chose to share it despite his enslaved status
• Why it mattered: this single exchange set in motion Mather's years-long effort to convince Boston's physicians to adopt variolation, ultimately reaching Boylston during the 1721 epidemic
• Strong answers will connect: the personal risk Onesimus took in offering this knowledge to the man who enslaved him, and how the practice's later success depended entirely on this initial exchange

Question 9. Explain the practice of variolation in your own words, including where it originated and how it worked.

A strong answer should include:

• Where it originated: variolation had been practiced across parts of West Africa for generations before Onesimus described it to Cotton Mather in colonial Boston [1]Best, Michael. "Note: Cotton Mather, Onesimus, and the Origins of Inoculation." Journal of the History of Medicine and Allied Sciences, vol. 66, no. 4, 2011.
• How it worked: a small amount of live smallpox virus was deliberately introduced into a healthy person's body, typically through a scratch or incision in the skin [2]Mather, Cotton. An Account of the Method and Success of Inoculating the Small-Pox in Boston in New-England. London, 1722.
• The result: the body developed a milder, controlled infection that trained the immune system to fight the disease, producing lifelong immunity without the high mortality risk of naturally contracted smallpox
• Strong answers will note: this is distinct from Edward Jenner's later vaccine, which used cowpox material rather than live smallpox virus [8]World Health Organization. "History of Smallpox Vaccination." who.int historical archive.

Question 10. The lesson argues "The knowledge came from Africa. The credit did not." Using at least two specific examples, explain what evidence in the lesson supports this claim.

A strong answer should include:

• At least two specific examples: Onesimus was nearly forgotten by history despite originating the knowledge; Zabdiel Boylston and Edward Jenner were remembered and credited for applying or building on that same knowledge [3]Boylston, Zabdiel. An Historical Account of the Small-Pox Inoculated in New England. London, 1726.[8]World Health Organization. "History of Smallpox Vaccination." who.int historical archive.
• What makes it a pattern rather than a coincidence: Boston refused to credit Onesimus even after the evidence from Boylston's patients proved the practice worked, and the practice went on to spread well beyond Boston [5]Miller, Genevieve. The Adoption of Inoculation for Smallpox in England and France. Philadelphia: University of Pennsylvania Press, 1957.
• What the Continental Army detail adds as evidence: Washington's soldiers were inoculated using the same principle Onesimus described decades earlier, yet his name carried none of the credit for that life-saving decision [6]Fenn, Elizabeth A. Pox Americana: The Great Smallpox Epidemic of 1775–82. New York: Hill and Wang, 2001.
• Strong answers will connect: this pattern to the broader theme running through Hotep Creations' library — knowledge and contributions that originate with African or African diaspora individuals being adopted, credited elsewhere, and the original source erased from memory
