Question: Remment Lucas "Rem" Koolhaas (Dutch pronunciation: [rem ko:lha:s]; born 17 November 1944) is a Dutch architect, architectural theorist, urbanist and Professor in Practice of Architecture and Urban Design at the Graduate School of Design at Harvard University. Koolhaas studied at the Architectural Association School of Architecture in London and at Cornell University in Ithaca, New York. Koolhaas is the founding partner of OMA, and of its research-oriented counterpart AMO based in Rotterdam, the Netherlands. In 2005, he co-founded Volume Magazine together with Mark Wigley and Ole Bouman.

Following the signing of Treaties of Nice in May 2001, which made Brussels the de facto capital of the European Union, the then President of the European Commission, Romano Prodi and the Belgian Prime Minister Guy Verhofstadt invited Koolhaas to discuss the necessities and requirements of a European capital. During these talks and as an impetus for further discussion, Koolhaas and his think-tank AMO - an independent part of OMA - suggested the development of a visual language. This idea inspired a series of drawings and drafts, including the "Barcode". The barcode seeks to unite the flags of the EU member countries into a single, colourful symbol. In the current European flag, there is a fixed number of stars. In the barcode however, new Member States of the EU can be added without space constraints. Originally, the barcode displayed 15 EU countries. In 2004, the symbol was adapted to include the ten new Member States. Since the time of the first drafts of the barcode it has very rarely been officially used by commercial or political institutions. During the Austrian EU Presidency 2006, it was officially used for the first time. The logo was used for the EU information campaign, but was very negatively criticized. In addition to the initial uproar caused by the Estonian flag stripes being displayed incorrectly, the proposed flag failed to achieve its main objective as a symbol. Critics pointed the lack of capability to relate the signified (the mental concept, the European Union) with the signifier (the physical image, the stripes) as the major problem, as well as the presented justification for the order in which the color stripes were displayed (as every country in the EU should be regarded as equal in importance and priority).

Question: Lucy Stone (August 13, 1818 - October 18, 1893) was a prominent U.S. orator, abolitionist, and suffragist, and a vocal advocate and organizer promoting rights for women. In 1847, Stone became the first woman from Massachusetts to earn a college degree. She spoke out for women's rights and against slavery at a time when women were discouraged and prevented from public speaking. Stone was known for using her birth name after marriage, the custom at the time being for women to take their husband's surname.

In 1892, Stone was convinced to sit for a portrait in sculpture, rendered by Anne Whitney, sculptor and poet. Stone had previously protested the proposed portrait for more than a year, saying that the funds to engage an artist would be better spent on suffrage work. Stone finally yielded to pressure from Frances Willard, the New England Women's Club and some of her friends and neighbors in the Boston area, and sat while Whitney produced a bust. In February 1893, Stone invited her brother Frank and his wife Sarah to come see the bust, before it was shipped to Chicago for display at the upcoming World's Columbian Exposition. Stone went with her daughter to Chicago in May, 1893 and gave her last public speeches at the World's Congress of Representative Women where she saw a strong international involvement in women's congresses, with almost 500 women from 27 countries speaking at 81 meetings, and attendance topping 150,000 at the week-long event. Stone's immediate focus was on state referenda under consideration in New York and Nebraska. Stone presented a speech she had prepared entitled "The Progress of Fifty Years" wherein she described the milestones of change, and said "I think, with never-ending gratitude, that the young women of today do not and can never know at what price their right to free speech and to speak at all in public has been earned." Stone met with Carrie Chapman Catt and Abigail Scott Duniway to form a plan for organizing in Colorado, and Stone attended two days of meetings about getting a woman suffrage drive restarted in Kansas. Stone and her daughter returned home to Pope's Hill on May 28. Those who knew Stone well thought her voice was lacking strength. In August when she and her husband Harry wanted to take part in more meetings at the Exposition, she was too weak to go. Stone was diagnosed as suffering from advanced stomach cancer in September. She wrote final letters to friends and relatives. Having "prepared for death with serenity and an unwavering concern for the women's cause," Lucy Stone died on October 18, 1893, at the age of 75. At her funeral three days later, 1,100 people crowded the church, and hundreds more stood silently outside. Six women and six men served as pallbearers, including sculptor Anne Whitney, and Stone's old abolitionist friends Thomas Wentworth Higginson and Samuel Joseph May. Mourners lined the streets for a sight of the funeral procession, and front-page banner headlines ran in news accounts. Stone's death was the most widely reported of any American woman's up to that time. According to her wishes, her body was cremated, making her the first person cremated in Massachusetts, though a wait of over two months was undertaken while the crematorium at Forest Hills Cemetery could be completed. Stone's remains are inurned at Forest Hills; a chapel there is named after her.
