Marina Abramović (Serbian Cyrillic: Марина Абрамовић; born November 30, 1946) is a Belgrade-born New York-based Serbian performance artist who began her career in the early 1970s. Active for over three decades, she has recently begun to describe herself as the "grandmother of performance art". Abramović's work explores the relationship between performer and audience, the limits of the body, and the possibilities of the mind.

Marina Abramović's great uncle was Patriarch Varnava of the Serbian Orthodox Church. Both of her parents were Partisans during the Second World War: her father Vojo was a commander who was acclaimed as a national hero after the War; her mother Danica was a major in the army, and in the mid-sixties was Director of the Museum of the Revolution and Art in Belgrade.

Abramović's father left the family in 1964. In an interview published in 1998, she described how her "mother took complete military-style control of me and my brother. I was not allowed to leave the house after 10 o'clock at night till I was 29 years old. ... [A]ll the performances in Yugoslavia I did before 10 o'clock in the evening because I had to be home then. It's completely insane, but all of my cutting myself, whipping myself, burning myself, almost losing my life in the firestar, everything was done before 10 in the evening."

Johns Hopkins (May 19, 1795 – December 24, 1873) was an American entrepreneur, abolitionist and philanthropist of 19th-century Baltimore, Maryland.

His bequests founded numerous institutions bearing his name, including Johns Hopkins Hospital, Johns Hopkins University, Johns Hopkins School of Nursing, Johns Hopkins School of Medicine, and Johns Hopkins Bloomberg School of Public Health.

A biography entitled Johns Hopkins: A Silhouette written by his cousin, Helen Hopkins Thom, was published in 1929 by the Johns Hopkins University Press.

Johns Hopkins was born on May 19, 1795, to Samuel Hopkins (1759–1814) of Anne Arundel County, Maryland, and Hannah Janney (1774–1864), of Loudoun County, Virginia. Home was Whitehall, a 500-acre (two km²) tobacco plantation in Anne Arundel County. His first name derives from a maternal great-grandmother, Margaret Johns, who passed it on to her son.

The Hopkins family were members of the Society of Friends (Quakers). In 1807 they emancipated their slaves in accordance with their local Society decree, which called for freeing the able-bodied and caring for the others, who would remain at the plantation and provide labor as they could. The second eldest of eleven children, 12 year-old Johns was required to work on the farm, interrupting his formal education. From 1806 to 1809, he likely attended The Free School of Anne Arundel County, which was located in today's Davidsonville, Maryland.
