Jane Jacobs OC OOnt (born Jane Butzner; May 4, 1916 – April 25, 2006) was an American-Canadian journalist, author, and activist best known for her influence on urban studies. Her influential book The Death and Life of Great American Cities (1961) argued that urban renewal did not respect the needs of most city-dwellers. The book also introduced sociology concepts such as "eyes on the street" and "social capital".

Jacobs was well known for organizing grassroots efforts to protect existing neighborhoods from "slum clearance" – and particularly for her opposition to Robert Moses in his plans to overhaul her neighborhood, Greenwich Village. She was instrumental in the eventual cancellation of the Lower Manhattan Expressway, which would have passed directly through SoHo and Little Italy, and was arrested in 1968 for inciting a crowd at a public hearing on the project. After moving to Canada in 1968, she joined the opposition to the Spadina Expressway and the associated network of expressways in Toronto planned and under construction.

As a mother and a female writer who criticized experts in the male-dominated field of urban planning, Jacobs endured scorn from established figures, who called her a "housewife" and a "crazy dame." She did not have a college degree in urban planning, and was also criticized for being unscholarly and imprecise. She was accused of inattention to racial inequality, and her concept of "unslumming" has been compared with gentrification. (Wikipedia)

1916, September 16 a private in the 49th Canadian Infantry Battalion at Courcelette, France, during a bombing attack during the latter stages of the Battle of the Somme, while acting as bayonet man, he noted that bombs were running short and ran along the parados under heavy fire until he advanced into an enemy trench, throwing hand grenades and firing his rifle at point-blank range, inflicting heavy losses; the enemy, thinking that they were surrounded, surrendered - 62 prisoners were taken and 250 yards of enemy trench captured; his fingers had been blown off, but he did not have his wound dressed until he and two other men had escorted the prisoners back under fire and reported for duty.

Victoria Cross Citation:

“For most conspicuous bravery. During a bombing attack he was acting as bayonet man, and, knowing that bombs were running short, he ran along the parados under heavy fire until he was in close contact with the enemy, when he opened fire on them at point-blank range, and inflicted heavy loss.

The enemy, thinking they were surrounded, surrendered. Sixty-two prisoners were taken and 250 yards of enemy trench captured.

Before carrying out this very plucky act one of Private Kerr’s fingers had been blown off by a bomb.

Later, with two other men, he escorted back the prisoners under fire, and then returned to report himself for duty before having his wound dressed.”
