Problem: Ralph Waldo Emerson (May 25, 1803 - April 27, 1882) was an American essayist, lecturer, philosopher and poet who led the transcendentalist movement of the mid-19th century. He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and he disseminated his thoughts through dozens of published essays and more than 1,500 public lectures across the United States. Emerson gradually moved away from the religious and social beliefs of his contemporaries, formulating and expressing the philosophy of transcendentalism in his 1836 essay "Nature". Following this work, he gave a speech entitled "The American Scholar" in 1837, which Oliver Wendell Holmes Sr. considered to be America's "intellectual Declaration of Independence".

Emerson was staunchly opposed to slavery, but he did not appreciate being in the public limelight and was hesitant about lecturing on the subject. He did, however, give a number of lectures during the pre-Civil War years, beginning as early as November, 1837. A number of his friends and family members were more active abolitionists than he, at first, but from 1844 on, he took a more active role in opposing slavery. He gave a number of speeches and lectures, and notably welcomed John Brown to his home during Brown's visits to Concord. He voted for Abraham Lincoln in 1860, but Emerson was disappointed that Lincoln was more concerned about preserving the Union than eliminating slavery outright. Once the American Civil War broke out, Emerson made it clear that he believed in immediate emancipation of the slaves.  Around this time, in 1860, Emerson published The Conduct of Life, his seventh collection of essays. In this book, Emerson "grappled with some of the thorniest issues of the moment," and "his experience in the abolition ranks is a telling influence in his conclusions." In these essays Emerson strongly embraced the idea of war as a means of national rebirth: "Civil war, national bankruptcy, or revolution, [are] more rich in the central tones than languid years of prosperity."  Emerson visited Washington, D.C, at the end of January 1862. He gave a public lecture at the Smithsonian on January 31, 1862, and declared:, "The South calls slavery an institution... I call it destitution... Emancipation is the demand of civilization". The next day, February 1, his friend Charles Sumner took him to meet Lincoln at the White House. Lincoln was familiar with Emerson's work, having previously seen him lecture. Emerson's misgivings about Lincoln began to soften after this meeting. In 1865, he spoke at a memorial service held for Lincoln in Concord: "Old as history is, and manifold as are its tragedies, I doubt if any death has caused so much pain as this has caused, or will have caused, on its announcement." Emerson also met a number of high-ranking government officials, including Salmon P. Chase, the secretary of the treasury; Edward Bates, the attorney general; Edwin M. Stanton, the secretary of war; Gideon Welles, the secretary of the navy; and William Seward, the secretary of state.  On May 6, 1862, Emerson's protege Henry David Thoreau died of tuberculosis at the age of 44. Emerson delivered his eulogy. He often referred to Thoreau as his best friend, despite a falling-out that began in 1849 after Thoreau published A Week on the Concord and Merrimack Rivers. Another friend, Nathaniel Hawthorne, died two years after Thoreau, in 1864. Emerson served as a pallbearer when Hawthorne was buried in Concord, as Emerson wrote, "in a pomp of sunshine and verdure".  He was elected a Fellow of the American Academy of Arts and Sciences in 1864.

Did he participate in many lectures?

Answer with quotes: notably welcomed John Brown to his home during Brown's visits to Concord.

Question:
Redd Foxx was born John Elroy Sanford on December 9, 1922, in St. Louis, Missouri and raised on Chicago's South Side. His father, Fred Sanford, an electrician and auto mechanic from Hickman, Kentucky, left his family when Foxx was four years old. He was raised by his half-Seminole Indian mother, Mary Hughes from Ellisville, Mississippi, his grandmother and his minister. Foxx attended DuSable High School in Chicago's Bronzeville neighborhood with future Chicago mayor Harold Washington.
Foxx achieved his most widespread fame starring in the television sitcom Sanford and Son, an adaptation of the BBC series Steptoe and Son. He used his starring role on Sanford and Son to help get jobs for his acquaintances such as LaWanda Page, Slappy White, Gregory Sierra, Don Bexley, Beah Richards, Stymie Beard, Leroy Daniels, Ernest Mayhand and Noriyuki "Pat" Morita.  The series premiered on the NBC television network on January 14, 1972 and was broadcast for six seasons. The final episode aired on March 25, 1977. Foxx played the role of Fred G. Sanford ("Fred Sanford" was actually Foxx's father's and brother's name), while Foxx's co-star Demond Wilson played the role of his son Lamont. In this sitcom, Fred and Lamont were owners of a junk/salvage store in Watts who dealt with many humorous situations that would arise. The series was notable for its racial humor and overt prejudices which helped redefine the genre of black situation comedy.  The show also had several running gags. When angry with Lamont, Fred would often say "You big dummy" or would often fake heart attacks by putting his hand on his chest and saying (usually while looking up at the sky) "It's the big one, I'm coming to join ya honey/Elizabeth" (referring to his late wife). Fred would also complain about having "arthur-itis" to get out of working by showing Lamont his cramped hand. Foxx depicted a character in his 60s, although in real-life he was a decade younger.  Demond Wilson had responded if he kept in touch with everybody from Sanford & Son; esp. the series' star, himself, after the series was canceled: "No. I saw Redd Foxx once before he died, circa 1983, and I never saw him again. At the time I was playing tennis at the Malibu Racquet Club and I was approached by some producers about doing a Redd Foxx 50th Anniversary Special. I hadn't spoken to him since 1977, and I called the club where (Redd) was playing. And we met at Redd's office, but he was less than affable. I told those guys it was a bad idea. I never had a cross word with him. People say I'm protective of Redd Foxx in my book (Second Banana, Wilson's memoir of the Sanford years). I had no animosity toward Foxx for (quitting the show in 1977) because I had a million dollar contract at CBS to do Baby I'm Back. My hurt was that he didn't come to me about throwing the towel in - I found out in the hallway at NBC from a newscaster. I forgave him and I loved Redd, but I never forgot that. The love was there. You can watch any episode and see that."
