Some context: Ludwig Mies van der Rohe ( MEESS; German: [mi:s]; born Maria Ludwig Michael Mies; March 27, 1886 - August 17, 1969) was a German-American architect. He is commonly referred to and was addressed as Mies, his surname.
Mies served as the last director of Berlin's Bauhaus, and then headed the department of architecture, Illinois Institute of Technology in Chicago, where he developed the Second Chicago School. He played a significant role as an educator, believing his architectural language could be learned, then applied to design any type of modern building. He set up a new education at the department of architecture of the Illinois Institute of Technology in Chicago replacing the traditional Ecole des Beaux-Art curriculum by a three-step-education beginning with crafts of drawing and construction leading to planning skills and finishing with theory of architecture (compare Vitruvius: firmitas, utilitas, venustas). He worked personally and intensively on prototype solutions, and then allowed his students, both in school and his office, to develop derivative solutions for specific projects under his guidance.  Some of Mies' curriculum is still put in practice in the first and second year programs at IIT, including the precise drafting of brick construction details so unpopular with aspiring student architects. When none was able to match the quality of his own work, he agonized about where his educational method had gone wrong. Nevertheless, his achievements in creating a teachable architecture language that can be used to express the modern technological era survives until today.  Mies placed great importance on education of architects who could carry on his design principles. He devoted a great deal of time and effort leading the architecture program at IIT. Mies served on the initial Advisory Board of the Graham Foundation in Chicago. His own practice was based on intensive personal involvement in design efforts to create prototype solutions for building types (860 Lake Shore Drive, the Farnsworth House, Seagram Building, S. R. Crown Hall, The New National Gallery), then allowing his studio designers to develop derivative buildings under his supervision.  Mies's grandson Dirk Lohan and two partners led the firm after he died in 1969. Lohan, who had collaborated with Mies on the New National Gallery, continued with existing projects but soon led the firm on his own independent path. Other disciples continued Mies's architectural language for years, notably Gene Summers, David Haid, Myron Goldsmith, Y.C. Wong, Jacques Brownson, and other architects at the firms of C.F. Murphy and Skidmore, Owings & Merrill.  But while Mies' work had enormous influence and critical recognition, his approach failed to sustain a creative force as a style after his death and was eclipsed by the new wave of Post Modernism by the 1980s. Proponents of the Post Modern style attacked the Modernism with clever statements such as "less is a bore" and with captivating images such as Crown Hall sinking in Lake Michigan. Mies had hoped his architecture would serve as a universal model that could be easily imitated, but the aesthetic power of his best buildings proved impossible to match, instead resulting mostly in drab and uninspired structures rejected by the general public. The failure of his followers to meet his high standard may have contributed to demise of Modernism and the rise of new competing design theories following his death.

Some context: Joe Frazier was the 12th child born to Dolly Alston-Frazier and Rubin in Beaufort, South Carolina. He was raised in a rural community of Beaufort called Laurel Bay. Frazier said he was always close to his father, who carried him when he was a toddler "over the 10 acres of farmland" the Fraziers worked as sharecroppers "to the still where he made his bootleg corn liquor, and into town on Saturdays to buy the necessities that a family of 10 needed." Young Frazier was affectionately called "Billie Boy."
According to an article from The New York Times, "over the years, Frazier has lost a fortune through a combination of his own generosity and naivete, his carousing, and failed business opportunities. The other headliners from his fighting days--Ali, George Foreman, and Larry Holmes--are millionaires." Asked about his situation, Frazier became playfully defensive, but would not reveal his financial status. "Are you asking me how much money I have?" he said. "I got plenty of money. I got a stack of $100 bills rolled up over there in the back of the room." Frazier blamed himself, partly, for not effectively promoting his own image. In a 2006 HBO documentary on the fight in Manila, Frazier was interviewed living in a one-room apartment on the second floor of his gym.  His daughter Jackie Frazier-Lyde is a lawyer and worked on her father's behalf in pursuit of money they claimed he was owed in a Pennsylvania land deal. In 1973, Frazier purchased 140 acres in Bucks County, Pennsylvania for $843,000. Five years later, a developer agreed to buy the farmland for $1.8 million. Frazier received annual payments from a trust that bought the land with money he had earned in the ring. However, when the trust went bankrupt, the payments ceased.  Frazier sued his business partners, insisting his signature had been forged on documents and he had no knowledge of the sale. In the ensuing years, the 140 acres was subdivided and turned into a residential community. The land is now worth an estimated $100 million.
