Question: How old was Dean Martin when Columbia Pictures acquired the rights to the Matt Helm novels? Passage 1:Daubenton was born at Montbard (Côte-d'Or). His father, Jean Daubenton, a notary, intended him for the church, and sent him to Paris to study theology, but Louis-Jean-Marie was more interested in medicine. Jean's death in 1736 set his son free to choose his own career, and in 1741 he graduated in medicine at Reims and returned to his hometown, planning to practice as a physician. At about this time, Georges-Louis Leclerc de Buffon, also a native of Montbard, was preparing to bring out a multi-volume work on natural history, the Histoire naturelle, générale et particulière, and in 1742 he invited Daubenton to assist him by providing anatomical descriptions. In many respects, the two men were complete opposites, but they worked well in partnership. In 1744, Daubenton became a member of the French Academy of Sciences as an adjunct botanist, and Buffon appointed him keeper and demonstrator of the king's cabinet in the Jardin du Roi.
 Passage 2:In 1965, Columbia Pictures acquired the film rights to eight Matt Helm novels. A five-film parody or spoof spy movie series was planned and four were made, debuting with The Silencers (from Hamilton's novels The Silencers and Death of a Citizen, adapted by acclaimed A Streetcar Named Desire screenwriter Oscar Saul). They were made to star Dean Martin, who co-produced with his Meadway-Claude Production company and received a partnership in the films. The series was produced by Irving Allen, who had once been the partner of James Bond film producer Albert R. "Cubby" Broccoli—the same man who had told Ian Fleming that his 007 novels were not "good enough for television," a point of contention between the two producers from 1958-1960 when they dissolved Warwick Films and went their separate ways.
 Passage 3:It was founded around 1072 as a Benedictine priory by William FitzOsbern and his son Roger de Breteuil, 2nd Earl of Hereford. FitzOsbern had been granted the Lordship of Striguil by his second cousin King William in gratitude for his support in the Norman conquest of England, and was responsible for starting the building of a new castle overlooking the River Wye on the border with the kingdoms of Wales. At the same time he established a nearby monastic cell, so as to collect rent from the lands within Gwent which he had granted to his home Priory of Cormeilles in Normandy. By the early 12th century, the monastic establishment, on a ridge overlooking the river about 300 metres from the castle, had the status of an alien priory in its own right, though it probably never held more than about 12 monks. It superseded an earlier Augustinian priory located about 2 km away, which was dedicated to the Welsh saint Cynfarch (or St. Kingsmark), a disciple of St. Dyfrig.
