Puerto Rico and the American Plantation System

I recently led a workshop and artist talk titled “Woodblock Prints and Medicine: Sugar and Tobacco in the Caribbean” based on my research, sourcing materials from UCSF’s Industry Documents Library (IDL), IDL’s Sugar Collection, and Japanese Woodblock Print Collection. These long-standing plantations harvested an economy that brought industry, and advancements in manufacturing and medicine, built on a system of slavery and exploitation. The documents exposed the unrelenting treatment of the Puerto Rican people and the growth of the massive pharmaceutical industry at the hands of colonial powers. Showing these stories through Ukiyo-e style woodblock prints supports the idea that our bodies are floating worlds, with each of our systems and organs characterized as a person or scene. These depictions draw connections within the human body regarding health, trauma, and diseases. The following images are attributions based on the original Japanese woodblock prints seen above each of my renderings.

Los diez principios de la eugenesia

The first image, Los diez principios de la eugenesia is based on Kuniteru Utagawa III’s, Tainai jukkai no zu (Ten realms within the body), 1885.

An explanation of the internal world of the woman, starting from the top-center and moving clockwise, is listed below:

  1. Teaching birth control methods to other women in Puerto Rico circa 1960.
  2. Enovid, the first combined oral contraceptive pill marketed for menstrual relief with a side effect of preventing pregnancy.
  3. Dr. John Rock, a scientist recruited to help Dr. Gregory Pincus investigate the clinical use of progesterone to prevent ovulation (Pincus, 1968).
  4. The chemical structure of Enovid, Mestranol, plus Noretynodrel.
  5. Injections of the hormone progesterone prevented ovulation in rabbits used in Gregory Pincus and Dr. M.C. Chang’s experiments. Progesterone prepares a fertilized egg for implantation into the uterus and shuts down the ovaries so no more eggs are released. There were many reasons scientists had not injected humans, some of them being there were too many risks, and progesterone was very expensive (Roberts, 2015).
  6. The hand of death transferring a pill to an unsuspecting recipient.
  7. A dog mauls a Taino woman during a mass attack from colonial forces.
  8. La Perla, a shanty town for enslaved people, servants, farmers, and later workers, is located by a cemetery.
  9. Dr. Gregory “Goodie” Pincus, the proclaimed “Father of Birth Control.”
  10. A sugarcane factory signifying the end of the agrarian system and the initiation of Operation Bootstrap.

A brief colonial history in Puerto Rico

Women and children have historically been the targets of unethical practices. These vulnerable populations directly reflect the trauma brought forth by the sugar and tobacco industries, which paved the way for the now pharmaceutical sector (Supreme Court, 1995). These industries have affected the island’s population through diabetes, addiction, and death.

Spain started the sugar plantation system only two decades after they colonized Puerto Rico. From 1493 to 1898, as many as 789 sugar plantations had land dedicated to commercial agriculture across the island (Malone & Morton, 2021). The Treaty of Paris of 1898 forced Spain to cede Puerto Rico to the U.S., which allowed the U.S. to appoint a civilian governor under the Foraker Act, Charles Herbert Allen, and placed the island under military rule. Allen was a corrupt businessman with no background in governmental practices and policies. He slashed operating expenses on the island, refusing to use the budget surplus to make essential infrastructure and education investments. With the extra funds, he instead re-directed them to no-bid contracts for U.S. businessmen, building roads at double the cost, railroad subsidies for U.S.-owned sugar plantations (his father owned Otis Allen and Son, a lumber business that created wooden boxes and sold railroad ties, housing frames, and road building materials), and high salaries for U.S. bureaucrats in the island government (Allen & McKinley, 1901). He was also listed as one of the “Politicians in the Lumber and Timber Business in Puerto Rico” (Library of Congress). In the single year Allen was governor, he managed to appoint half of the offices in the government to visiting Americans (626 individuals), and nearly all the Executive Council were U.S. expatriates (Maldonado-Denis, 1972).

In 1901, Allen resigned as governor, fled to Wall Street, and joined the House of Morgan (J.P. Morgan & Co.) and the Guaranty Trust Company of New York as their vice president. In 1907 he created the world’s largest sugar syndicate in Puerto Rico, the American Sugar Refining Company (later the Sugar Trust). This Trust owned and controlled 98% of the sugar processing capacity in the United States. Allen’s political appointees in Puerto Rico provided him with land grants, tax subsidies, water rights, railroad easements, foreclosure sales, and favorable tariffs (Tovar et al., 1971). By 1930, Allen and his banking partners converted 45% of all arable land into sugar plantations. They owned the insular postal system, the entire coastal railroad, and the international seaport of San Juan. Today, the syndicate is known as Domino Sugar.

These forms of governmental nepotistic and unethical business models have continued ’til today in the form of massive tax breaks to large pharmaceutical companies (over $250 billion between 2017 and 2023). The U.S. government claims that creating a big pharmaceutical haven in Puerto Rico would create jobs and support communities. However, only roughly 7,000 jobs have been created, and many workers face low wages, inadequate benefits, and poor workplace safety. The exploitation model of the sugarcane plantations has synthesized itself into a new, addictive behemoth- the pharmaceutical industry of the American empire (Varona, 2022).

El Maestro y la esperanza de una nación

The second image, entitled El Maestro y la esperanza de una nación is inspired by Nozoki Shōshiki Rodonsai’s, Shinō kōshō gozō no nazorae (Suffering, death, and effective life: metaphorical classifying organs according to 4 levels of social status, shinō kōs hō (samurai, farmer, artisan, merchant) from the late 19th century.

“El Maestro y la esperanza de una nación” examines the various levels of social hierarchy in the Caribbean-European plantation system. The scenes in the stomach are encapsulated by a man known as Pedro Albizu Campos, a Puerto Rican attorney, social activist, and nationalist. He led an island-wide agricultural strike, with over 85 rallies in 1933 alone, which created awareness around the sugarcane, tobacco, needlework, and transportation industries. These rallies intended to raise sugarcane worker wages from $0.45 to $1.50 per 12-hour day (Villanueva, 2009). His efforts to teach and encourage others to fight for freedom and sovereignty led to 24-hour surveillance by FBI officials, a gag law, and 25 years of imprisonment which led to his eventual death by radiation experimentation, seen in his inflamed foot. These lethal doses of radiation caused welts, burns, and cerebral thrombosis.

Descriptions of the scenes can be seen below, starting from the top-center and moving clockwise.

  1. A large plantation of tobacco crops. To the right are enslaved people and indentured servants carrying cow manure in bags on their heads. Their children help with odds and ends.
  2. A worker cuts grass to ready the land for the next season of crops. Behind him lay large bundles of sugarcane. 
  3. A plantation owner/ politician counts and tracks their profits as they sit beside a pile of money.

Cornelius P. Rhoads, an instructor of Pathology at Harvard and staff at Rockefeller University and Hospital, sits to the right of these scenes. He is draped in a skull-and-crossbones kimono, looking at a red pill, which represents his vehement support of contraceptives on the island, along with his six-month stint in 1932 injecting cancer cells into the Puerto Rican people. He also experimentally altered his subjects’ (or, as he would refer to them, “experimental animals”) diets to induce the conditions he researched instead of treating the ailments (Lederer, 2002). An excerpt from his letter follows: “They [Porto Ricans] are beyond doubt the dirtiest, laziest, most degenerate, and thievish race of men ever inhabiting this sphere. It makes you sick to inhabit the same island with them. They are even lower than Italians. What the island needs is not public health work but a tidal wave or something to totally exterminate the population. It might then be livable. I have done my best to further the process of extermination by killing off 8 and transplanting cancer into several more. The latter has not resulted in any fatalities so far… The matter of consideration for the patients’ welfare plays no role here — in fact, all physicians take delight in the abuse and torture of the unfortunate subjects” (Rosenthal, 2003). This letter was given to Pedro Albizu Campos, who distributed it worldwide to various media outlets. Albizu believed that Rhodes was part of a larger U.S. government plot to exterminate Puerto Ricans.

The Industry Documents Library and IDL’s Sugar Collection resources have added important context and supporting documentation to my research. Much of Puerto Rico’s history has been downplayed or covered up due to corrupt politicians and special interests. Utilizing the Japanese Woodblock Collection has also had an insightful impact on my project and process by creating approachable images for complex topics. The next workshop will cover traditional Japanese woodblock techniques using chisels, ink, and hand-printing. I will also touch on the technological aspects of this project and the works created through The Makers Lab at UCSF.
