Frederick Douglass (born Frederick Augustus Washington Bailey; c. February 1818 - February 20, 1895) was an African-American social reformer, abolitionist, orator, writer, and statesman. After escaping from slavery in Maryland, he became a national leader of the abolitionist movement in Massachusetts and New York, gaining note for his oratory and incisive antislavery writings. In his time, he was described by abolitionists as a living counter-example to slaveholders' arguments that slaves lacked the intellectual capacity to function as independent American citizens. Northerners at the time found it hard to believe that such a great orator had once been a slave.
After returning to the U.S. in 1847, Douglass started publishing his first abolitionist newspaper, the North Star, from the basement of the Memorial AME Zion Church in Rochester, New York. The North Star's motto was "Right is of no Sex - Truth is of no Color - God is the Father of us all, and we are all brethren." The AME Church and North Star vigorously opposed the mostly white American Colonization Society and its proposal to send blacks back to Africa. This and Douglass's later abolitionist newspapers were mainly funded by English supporters, who gave Douglass five hundred pounds to use as he chose. Douglass also soon split with Garrison, perhaps because the North Star competed with Garrison's National Anti-Slavery Standard and Marius Robinson's Anti-Slavery Bugle.  Douglass also came to consider Garrison too radical. Earlier Douglass had agreed with Garrison's position that the Constitution was pro-slavery, because of its compromises related to apportionment of Congressional seats, based on partial counting of slave populations with state totals; and protection of the international slave trade through 1807. Garrison had burned copies of the Constitution to express his opinion. But, Lysander Spooner published The Unconstitutionality of Slavery (1846), which explored the United States Constitution as an anti-slavery document. Douglass's change of opinion about the Constitution and his splitting from Garrison around 1847 became one of the abolitionist movement's most notable divisions. Douglass angered Garrison by saying that the Constitution could and should be used as an instrument in the fight against slavery.  In September 1848, Douglass published an open letter addressed to his former master, Thomas Auld, berating him for his conduct, and enquiring after members of his family still held by Auld. In a graphic passage, Douglass asked Auld how he would feel if Douglass had come to take away his daughter Amanda as a slave, treating her the way he and members of his family had been treated by Auld.

Answer the question at the end by quoting:

Federico Fellini, Cavaliere di Gran Croce OMRI (Italian: [fede'ri:ko fel'li:ni]; 20 January 1920 - 31 October 1993) was an Italian film director and screenwriter. Known for his distinct style that blends fantasy and baroque images with earthiness, he is recognized as one of the greatest and most influential filmmakers of all time. His films have ranked, in polls such as Cahiers du cinema and Sight & Sound, as some of the greatest films of all time. Sight & Sound lists his 1963 film 8 1/2  as the 10th-greatest film of all time.
Retained on business in Rimini, Urbano sent wife and family to Rome in 1940 to share an apartment with his son. Fellini and Ruggero Maccari, also on the staff of Marc'Aurelio, began writing radio sketches and gags for films.  Not yet twenty and with Fabrizi's help, Fellini obtained his first screen credit as a comedy writer on Mario Mattoli's Il pirata sono io (The Pirate's Dream). Progressing rapidly to numerous collaborations on films at Cinecitta, his circle of professional acquaintances widened to include novelist Vitaliano Brancati and scriptwriter Piero Tellini. In the wake of Mussolini's declaration of war against France and England on 10 June 1940, Fellini discovered Kafka's The Metamorphosis, Gogol, John Steinbeck and William Faulkner along with French films by Marcel Carne, Rene Clair, and Julien Duvivier. In 1941 he published Il mio amico Pasqualino, a 74-page booklet in ten chapters describing the absurd adventures of Pasqualino, an alter ego.  Writing for radio while attempting to avoid the draft, Fellini met his future wife Giulietta Masina in a studio office at the Italian public radio broadcaster EIAR in the autumn of 1942. Well-paid as the voice of Pallina in Fellini's radio serial, Cico and Pallina, Masina was also well known for her musical-comedy broadcasts which cheered an audience depressed by the war. In November 1942, Fellini was sent to Libya, occupied by Fascist Italy, to work on the screenplay of I cavalieri del deserto (Knights of the Desert, 1942), directed by Osvaldo Valenti and Gino Talamo. Fellini welcomed the assignment as it allowed him "to secure another extension on his draft order". Responsible for emergency re-writing, he also directed the film's first scenes. When Tripoli fell under siege by British forces, he and his colleagues made a narrow escape by boarding a German military plane flying to Sicily. His African adventure, later published in Marc'Aurelio as "The First Flight", marked "the emergence of a new Fellini, no longer just a screenwriter, working and sketching at his desk, but a filmmaker out in the field".  The apolitical Fellini was finally freed of the draft when an Allied air raid over Bologna destroyed his medical records. Fellini and Giulietta hid in her aunt's apartment until Mussolini's fall on 25 July 1943. After dating for nine months, the couple were married on 30 October 1943. Several months later, Masina fell down the stairs and suffered a miscarriage. She gave birth to a son, Pierfederico, on 22 March 1945, but the child died of encephalitis a month later on 24 April 1945. The tragedy had enduring emotional and artistic repercussions.

Did he work on it by himself?
