Context paragraphs:
Brooklyn Theatre fire: The Brooklyn Theatre Fire was a catastrophic theatre fire that broke out on the evening of December 5, 1876, in the then-city of Brooklyn (now a borough of New York City).  The conflagration killed at least 278 individuals, with some accounts reporting more than 300 dead.  One hundred and three unidentified victims were interred in a common grave at Green-Wood Cemetery.  An obelisk near the main entrance at Fifth Avenue and 25th Street marks the burial site.  More than two dozen identified victims were interred individually in separate sections at the Cemetery of the Evergreens in Brooklyn.

2002 El Ayyat railway accident: The El Ayyat train disaster happened at 02:00 on the morning of 20 February 2002 in an eleven-carriage passenger train travelling from Cairo to Luxor.  A cooking gas cylinder exploded in the fifth carriage, creating a fire which engulfed seven third-class carriages, reducing them almost to cinders.  The initial number of dead given by officials at the time was 383, all Egyptians.  However, considering that seven carriages were burnt to the ground, and each carriage was packed with at least double the maximum carrying capacity of 150, this number is considered by many people to be a great underestimate.  The dubious nature of the given death toll lies with the absence of a full passenger list; accounting for those missing was almost impossible at the time.  In addition, the fire was so intense and the carriages so badly burned that many corpses had been reduced to ash.  As there was no means of communication between the driver and the rear carriages, the driver did not know of the fire until about two hours after it had begun, resulting in many people, attempting to flee from the overcrowded carriages, jumping to their death.  Some important Egyptians have commentated that the official number of 383 dead is grossly inaccurate and was an attempt to lessen the damage done to the reputation of the government.  Many people consider a number of about 1000 deaths to be more accurate.

Sarah Crocker Conway: Sarah Crocker Conway (b. Ridgefield, Connecticut, 1834; d. Brooklyn, New York, April 28, 1875) was an actress.  She was a sister of Elizabeth Crocker Bowers, also an actress.  She made her debut in Baltimore, Maryland in 1849, playing Parthenia and other leading parts.  In May 1852, she married the actor Frederick B. Conway, and the two thenceforward acted together.  In 1859, they opened Pike's Opera House in Cincinnati, Ohio with a first-class company, but the engagement was not profitable, and they returned to the east.  In 1861, they visited England, and filled a short engagement at Sadler's Wells Theatre, London.  After their return, they became star actors, and made an extensive and profitable tour.  In 1864 Sarah leased the Park Theatre in Brooklyn, and subsequently the new Brooklyn Theatre, in which for nine years her husband played leading parts.  Sarah Conway possessed a tall and graceful figure and an expressive countenance, and was a versatile actress and a popular theatre manager.

Conway Tearle: Frederick Conway Levy was born on May 17, 1878, in New York City, the son of the well-known British-born cornetist Jules Levy (1838–1903) and American actress Marianne “Minnie” Conway (1852–1896).  Tearle also had a sister, and a half-brother, musician Jules Levy, Jr., from his father's previous marriage.  Minnie's mother was stage actress Sarah Crocker Conway.  Minnie Conway was a direct descendant of William Augustus Conway, a British Shakespearian actor who became popular in America during the 1820s.  Her father, the proprietor of the Brooklyn Theatre, was said to have organized the first stock company in America.  After Tearle’s parents separated, his mother married Osmond Tearle (1852–1901), a British Shakespearian actor popular in “the provinces”.  Two half brothers, Godfrey and Malcolm Tearle, were born from Marianne's marriage to Osmond Tearle.

1866 Great fire of Portland, Maine: The great fire of Portland, Maine sometimes known as the 1866 Great fire of Portland in Maine occurred on July 4, 1866—the first Independence Day after the end of the American Civil War.  Five years before the Great Chicago Fire, this was the greatest fire yet seen in an American city.  It started in a boat house on Commercial Street, likely caused by a firecracker or a cigar ash.  The fire spread to a lumber yard and on to a sugar house, then spread across the city, eventually burning out on Munjoy Hill in the city's east end.  Two people died in the fire.  Ten thousand people were made homeless and 1,800 buildings were burned to the ground.  This included the federal Exchange Building by which was replaced with the custom house.  Soon after the fire, poet Henry Wadsworth Longfellow described his old home town: "Desolation!  Desolation!  Desolation!  It reminds me of Pompeii, the 'sepult city'."

Great Fire of Northampton: The Great Fire of Northampton occurred in September 1675 in Northampton in Northamptonshire, England.  The blaze was caused by sparks from an open fire in St. Mary’s Street, near Northampton Castle.  The fire devastated the town centre, destroying about 700 buildings [out of 850] including All Saints church, in six hours.  Three quarters of the town was destroyed, 11 people died and about 700 families were made homeless.  Many people escaped the fire by going through Welsh House on the market square to safety.

Jeff Strabone: Jeff Strabone is a Brooklyn-based American scholar, political activist and civic leader.  In 2016, his website "directelection.org" listed the names and addresses of members of the U.S. Electoral College, and he urged people to write to electors to ask them not to vote for president-elect Donald Trump, an effort which brought him national attention.

He has been a leader of Brooklyn's Cobble Hill Association, a neighborhood preservation group.  He is the co-founder and chairman of the New Brooklyn Theatre.

He early developed a taste for the stage.  After he had won a fair position in his profession in England, he came to the United States in August 1850.  Here he formed an association with Edwin Forrest, and played Iago to his "Othello", de Mauprat to his "Richelieu", and other companion parts.

In 1861, they visited England, and filled a short engagement at Sadler's Wells Theatre, London.  After their return they became star actors, and made an extensive and profitable tour.
