Context and question: William Henry Perkin studied and worked at the college under von Hofmann, but resigned his position after discovering the first synthetic dye, mauveine, in 1856. Perkin's discovery was prompted by his work with von Hofmann on the substance aniline, derived from coal tar, and it was this breakthrough which sparked the synthetic dye industry, a boom which some historians have labelled the second chemical revolution. His contribution led to the creation of the Perkin Medal, an award given annually by the Society of Chemical Industry to a scientist residing in the United States for an "innovation in applied chemistry resulting in outstanding commercial development". It is considered the highest honour given in the industrial chemical industry.
Who discovered the first synthetic dye?
Answer: William Henry Perkin
Context and question: The popularity of this particular representation of The Immaculate Conception spread across the rest of Europe, and has since remained the best known artistic depiction of the concept: in a heavenly realm, moments after her creation, the spirit of Mary (in the form of a young woman) looks up in awe at (or bows her head to) God. The moon is under her feet and a halo of twelve stars surround her head, possibly a reference to "a woman clothed with the sun" from Revelation 12:1-2. Additional imagery may include clouds, a golden light, and cherubs. In some paintings the cherubim are holding lilies and roses, flowers often associated with Mary.
Where is Mary depicted before her creation?

Context and question: Support for the U.S. cooled when America made clear its determination to invade Iraq in late 2002. Even so, many of the "coalition of the willing" countries that unconditionally supported the U.S.-led military action have sent troops to Afghanistan, particular neighboring Pakistan, which has disowned its earlier support for the Taliban and contributed tens of thousands of soldiers to the conflict. Pakistan was also engaged in the War in North-West Pakistan (Waziristan War). Supported by U.S. intelligence, Pakistan was attempting to remove the Taliban insurgency and al-Qaeda element from the northern tribal areas.
What action made support for the US increase?
