Problem: John Charles Fremont or Fremont (January 21, 1813 - July 13, 1890) was an American explorer, politician, and soldier who, in 1856, became the first candidate of the Republican Party for the office of President of the United States. During the 1840s, when he led five expeditions into the American West, that era's penny press and admiring historians accorded Fremont the sobriquet The Pathfinder. During the Mexican-American War, Fremont, a major in the U.S. Army, took control of California from the California Republic in 1846.

In the fall of 1853, Fremont embarked on another expedition to identify a viable route for a transcontinental railroad along the 38th parallel. The party journeyed between Missouri and San Francisco, California, over a combination of known trails and unexplored terrain. A primary objective was to pass through the Rocky Mountains and Sierra Nevada Mountains during winter to document the amount of snow and the feasibility of winter rail passage along the route. His photographer (daguerreotypist) was Solomon Nunes Carvalho.  Fremont followed the Santa Fe Trail, passing Bent's Fort before heading west and entering the San Luis Valley of Colorado in December. The party then followed the North Branch of the Old Spanish Trail, crossing the Continental Divide at Cochetopa Pass and continuing west into central Utah. But following the trail was made difficult by snow cover. On occasion, they were able to detect evidence of Captain John Gunnison's expedition, which had followed the North Branch just months before.  Weeks of snow and bitter cold took its toll and slowed progress. Nonessential equipment was abandoned and one man died before the struggling party reached the Mormon settlement of Parowan in southwestern Utah on February 8, 1854. After spending two weeks in Parowan to regain strength, the party continued across the Great Basin and entered the Owens Valley near present-day Big Pine, California. Fremont then journeyed south and crossed the Sierra Nevada Mountains and entered the Kern River drainage, which was followed west to the San Joaquin Valley.  Fremont arrived in San Francisco on April 16, 1854. Having completed a winter passage across the mountainous west, Fremont was optimistic that a railroad along the 38th Parallel was viable and that winter travel along the line would be possible through the Rocky Mountains.

What did he do towards the end of 1854?

Answer with quotes: Fremont arrived in San Francisco on April 16, 1854.

Question:
The Birth of a Nation (originally called The Clansman) is a 1915 American silent epic drama film directed and co-produced by D. W. Griffith and starring Lillian Gish. The screenplay is adapted from the novel and play The Clansman, both by Thomas Dixon Jr., as well as Dixon's novel The Leopard's Spots. Griffith co-wrote the screenplay with Frank E. Woods, and co-produced the film with Harry Aitken. It was released on February 8, 1915.
Thomas Dixon, Jr. was a former classmate of then-president Woodrow Wilson at Johns Hopkins University. Dixon arranged a screening of The Birth of a Nation at the White House for Wilson, members of his cabinet, and their families, in one of the first ever screenings at the White House. Wilson was falsely reported to have said of the film, "It is like writing history with lightning. And my only regret is that it is all so terribly true". Wilson's aide, Joseph Tumulty, denied the claims and said that "the President was entirely unaware of the nature of the play before it was presented and at no time has expressed his approbation of it." Historians believe the quote attributed to Wilson originated with Dixon, who was relentless in publicizing the film. After controversy over the film had grown, Wilson wrote that he disapproved of the "unfortunate production".  Besides having the film screened at the White House, Dixon persuaded all nine justices of the Supreme Count to attend a screening of The Birth of a Nation as well as many members of Congress. With the help of the Navy Secretary, Josephus Daniels, Dixon was able to meet the Chief Justice of the Supreme Court, Edward Douglass White. Initially Justice White was not interested in seeing the film, but when Dixon told him it was the "true story" of Reconstruction and the Klan's role in "saving the South", White, recalling his youth in Louisiana, jumped to attention and said: "I was a member of the Klan, sir". With White agreeing to see the film, the rest of the Supreme Court followed. Dixon was clearly rattled and upset by criticism by African-Americans that the film version of his books was projecting hatred against them, and wanted the endorsement of many powerful men as possible to offset such criticism. Dixon always vehemently denied having anti-black prejudices--despite the way his books promoted white supremacy--and stated: "My books are hard reading for a Negro, and yet the Negroes, in denouncing them, are unwittingly denouncing one of their greatest friends".  In a letter sent on May 1, 1915, to Joseph P. Tumulty, the press secretary to President Wilson, Dixon wrote: "The real purpose of my film was to revolutionize Northern sentiments by a presentation of history that would transform every man in the audience into a good Democrat...Every man who comes out of the theater is a Southern partisan for life!" In a letter to President Wilson sent on September 5, 1915, Dixon boasted: "This play is transforming the entire population of the North and the West into sympathetic Southern voters. There will never be an issue of your segregation policy". Dixon was alluding to the fact that Wilson upon becoming president in 1913 had imposed segregation on federal workplaces in Washington D.C. while reducing the number of black employees through demotion or dismissal.
