Robert Joseph "Bob" Vila (b. June 20, 1946) is an American home improvement television show host known for This Old House (1979–1989), Bob Vila's Home Again (1990–2005), and Bob Vila (2005–2007).

Vila, a Cuban American native of Miami, Florida, received a Bachelor degree in entomology from the University of Florida in 1969. After graduating, he served as a volunteer in the Peace Corps, working in Panama from 1971 to 1973.

Vila was hired as the host of This Old House in 1979 after receiving the "Heritage House of 1978" award by Better Homes and Gardens, for his restoration of a Victorian Italianate house in Newton, Massachusetts. On This Old House, Vila appeared with carpenter Norm Abram as they, and others, renovated houses. In 1989 he left the show under controversial circumstances. Some cite the reason as being a series of conflicts with This Old House executive producer Russell Morash arising from his involvement with outside commercial endorsements, while others cite a specific instance- Vila's commercial work for New Jersey-based Rickel and the subsequent retaliatory pulling of underwriting from Rickel's competitor Home Depot and lumber supplier Weyerhaeuser- as the reason behind his departure. He was replaced by Steve Thomas.

Niccolò di Bernardo dei Machiavelli (Italian pronunciation: [nikkoˌlɔ makjaˈvɛlli], 3 May 1469 – 21 June 1527) was an Italian historian, diplomat, philosopher, humanist and writer based in Florence during the Renaissance. A founder of modern political science, he was a diplomat, political philosopher, playwright, and a civil servant of the Florentine Republic. He also wrote comedies, carnival songs, and poetry. His personal correspondence is renowned in the Italian language. He was Secretary to the Second Chancery of the Republic of Florence from 1498 to 1512, when the Medici were out of power. He wrote his masterpiece, The Prince after the Medici had recovered power and he no longer held a position of responsibility in Florence, and is respectively interpreted by many as a satire of these powers.

Machiavelli was born in Florence, Italy, the first son and third child of attorney, Bernardo di Niccolò Machiavelli, and his wife, Bartolomea di Stefano Nelli. The Machiavelli family are believed to be descended from the old marquesses of Tuscany and to have produced thirteen Florentine Gonfalonieres of Justice, one of the offices of a group of nine citizens selected by drawing lots every two months, who formed the government, or Signoria. Machiavelli, like many people of Florence, was however not a full citizen of Florence, due to the nature of Florentine citizenship in that time, even under the republican regime.

Antoine Brumel (c. 1460 – 1512 or 1513) was a French composer. He was one of the first renowned French members of the Franco-Flemish school of the Renaissance, and, after Josquin des Prez, was one of the most influential composers of his generation.

Little is known about his early life, but he was probably born west of Chartres, perhaps in the town of Brunelles, near to Nogent-le-Rotrou, making him one of the first of the Netherlandish composers who was actually French. He sang at Notre-Dame de Chartres from 9 August 1483 until 1486, and subsequently held posts at St Peter's in Geneva (until 1492) and Laon (around 1497) before becoming choirmaster to the boys at Notre-Dame de Paris from 1498 to 1500, and choirmaster to Alfonso I d'Este at Ferrara from 1506, replacing the famous composer Jacob Obrecht who had died of the plague there the previous year. The chapel there was disbanded in 1510, after which he evidently stayed in Italy; several documents connect him with churches in Faenza and Mantua, where he probably died in 1512 or shortly after. He is known to have written at least one work after his dismissal from Ferrara (the Missa de beata virgine), and he may have still have been alive in 1513 since there is a mention in a treatise of Vincenzo Galilei that Brumel was one of a group of composers who met with Pope Leo X in that year; however since Vincenzo was writing more than a generation later and reporting second-hand, and no other corroborating evidence has been found, this account is not considered to be certain. Then again, Heinrich Glareanus, writing later about Brumel, indicated that he lived to a "ripe old age", so it remains possible that he lived longer, but records have not survived.
