Answer the question at the end by quoting:

John Marshall (September 24, 1755 - July 6, 1835) was an American politician and the fourth Chief Justice of the United States (1801-1835). His court opinions helped lay the basis for United States constitutional law and many say he made the Supreme Court of the United States a coequal branch of government along with the legislative and executive branches. Previously, Marshall had been a leader of the Federalist Party in Virginia and served in the United States House of Representatives from 1799 to 1800. He was Secretary of State under President John Adams from 1800 to 1801 and, at the age of 45, became the last of the chief justices to be born in Colonial America.
In 1782, Marshall won a seat in the Virginia House of Delegates, in which he served until 1789 and again from 1795 to 1796. The Virginia General Assembly elected him to serve on the Council of State later in the same year. In 1785, Marshall took up the additional office of Recorder of the Richmond City Hustings Court.  In 1788, Marshall was selected as a delegate to the Virginia convention responsible for ratifying or rejecting the United States Constitution, which had been proposed by the Philadelphia Convention a year earlier. Together with James Madison and Edmund Randolph, Marshall led the fight for ratification. He was especially active in defense of Article III, which provides for the Federal judiciary. His most prominent opponent at the ratification convention was Anti-Federalist leader Patrick Henry. Ultimately, the convention approved the Constitution by a vote of 89-79. Marshall identified with the new Federalist Party (which supported a strong national government and commercial interests), and opposed Jefferson's Republican Party (which advocated states' rights and idealized the yeoman farmer and the French Revolution).  Meanwhile, Marshall's private law practice continued to flourish. He successfully represented the heirs of Lord Fairfax in Hite v. Fairfax (1786), an important Virginia Supreme Court case involving a large tract of land in the Northern Neck of Virginia. In 1796, he appeared before the United States Supreme Court in another important case, Ware v. Hylton, a case involving the validity of a Virginia law providing for the confiscation of debts owed to British subjects. Marshall argued that the law was a legitimate exercise of the state's power; however, the Supreme Court ruled against him, holding that the Treaty of Paris in combination with the Supremacy Clause of the Constitution required the collection of such debts.  Henry Flanders in his biography of Marshall remarked that Marshall's argument in Ware v. Hylton "elicited great admiration at the time of its delivery, and enlarged the circle of his reputation." Flanders also wrote that the reader "cannot fail to be impressed with the vigor, rigorous analysis, and close reasoning that mark every sentence of it."  In 1795, Marshall declined Washington's offer of Attorney General of the United States and, in 1796, declined to serve as minister to France.

What were some of the actions he took?

IN: Pink Floyd were an English rock band formed in London in 1965. They achieved international acclaim with their progressive and psychedelic music. Distinguished by their use of philosophical lyrics, sonic experimentation, extended compositions, and elaborate live shows, they are one of the most commercially successful and influential groups in popular music history. Pink Floyd were founded by students Syd Barrett on guitar and lead vocals, Nick Mason on drums, Roger Waters on bass and vocals, and Richard Wright on keyboards and vocals.

In December 1967, the group added guitarist David Gilmour as the fifth member of Pink Floyd. Gilmour already knew Barrett, having studied with him at Cambridge Tech in the early 1960s. The two had performed at lunchtimes together with guitars and harmonicas, and later hitch-hiked and busked their way around the south of France. In 1965, while a member of Joker's Wild, Gilmour had watched the Tea Set. Morrison's assistant, Steve O'Rourke, set Gilmour up in a room at O'Rourke's house with a salary of PS30 per week (equivalent to PS500 in 2016), and in January 1968, Blackhill Enterprises announced Gilmour as the band's newest member; the second guitarist and its fifth member, the band intending to continue with Barrett as a nonperforming songwriter. Jenner commented: "The idea was that Dave would ... cover for [Barrett's] eccentricities and when that got to be not workable, Syd was just going to write. Just to try to keep him involved". In an expression of his frustration, Barrett, who was expected to write additional hit singles to follow up "Arnold Layne" and "See Emily Play", instead introduced "Have You Got It Yet?" to the band, intentionally changing the structure on each performance so as to make the song impossible to follow and learn. In a January 1968 photo-shoot of the five-man Pink Floyd, the photographs show Barrett looking detached from the others, staring into the distance.  Working with Barrett eventually proved too difficult, and matters came to a conclusion in January while en route to a performance in Southampton when a band member asked if they should collect Barrett. According to Gilmour, the answer was "Nah, let's not bother", signalling the end of Barrett's tenure with Pink Floyd. Waters later admitted, "He was our friend, but most of the time we now wanted to strangle him". In early March 1968, Pink Floyd met with business partners Jenner and King to discuss the band's future; Barrett agreed to leave.  Jenner and King believed Barrett to be the creative genius of the band, and decided to represent him and end their relationship with Pink Floyd. Morrison then sold his business to NEMS Enterprises, and O'Rourke became the band's personal manager. Blackhill announced Barrett's departure on 6 April 1968. After Barrett's departure, the burden of lyrical composition and creative direction fell mostly on Waters. Initially, Gilmour mimed to Barrett's voice on the group's European TV appearances; however, while playing on the university circuit, they avoided Barrett songs in favour of Waters and Wright material such as "It Would Be So Nice" and "Careful with That Axe, Eugene".

Did Barrett leave under bad circumstances?
