Question: How old was Mary Holland when Magill magazine was launched? Passage 1:Bell grew up on a farm and helped to run the Church Farm caravan site, complete with its own pub, near Pagham Harbour before being encouraged by his stepfather Bernard Hender to take up racing with a Lotus Seven in 1964. He won his first race in the Lotus at Goodwood in March of that year. He graduated to Formula Three in the following year racing a Lotus 31 and in 1966 switched to a Lotus 41 scoring his first victory, again at Goodwood. In 1967 he enjoyed seven wins. He entered Formula Two in a privateer Brabham BT23C fielded by his stepfather's Church Farm Racing team and after several promising performances, which caught Enzo Ferrari's eye, made his Formula One Grand Prix debut for Ferrari at Monza in 1968. He contested the 1969 Tasman Series in a 2.4 Dino and was second at Lakeside to Amon and Rindt at Warwick Farm. In 1969 he raced the four-wheel-drive McLaren M9A in its only ever race at the British Grand Prix at Silverstone.
 Passage 2:Gümmenen Castle, of which nothing remains, was built by either the Counts of Burgundy or the Dukes of Zähringen as part of the defenses along the Saane, along with Laupen Castle and Grasburg Castle. The castle was built to defend a bridge over the river. By 1391, a village (villa inferiori Dicti castri) had developed around the bridge. In 1259, Peter of Savoy made Gümmenen into an imperial fief and imperial castellans took over the castle and village. In 1282–83 King Rudolph I of Germany forced the Savoy castellan out and granted it to a Habsburg knight, Ulrich II of Maggenberg as a fief. Ulrich's heirs sold the castle, ferry and ford to Fribourg in 1319. Fribourg then granted the lands to the knights of Vuippens, who lost it back to either the Holy Roman Empire or Fribourg in 1325. The castle and village were besieged and destroyed in 1333 during Bern and Fribourg's first war over the Sense and Saane valleys, the Gümmenenkrieg. The peace treaty brokered in 1333 by Queen Agnes returned Gümmenen to Fribourg.
 Passage 3:He launched Magill magazine in September 1977 with Noel Pearson and Mary Holland. Magill became Ireland's foremost investigative publication. Among its writers were Gene Kerrigan, Pat Brennan and Paddy Agnew. He remained editor of Magill until 1983, when he became involved in the relaunch of the Sunday Tribune with Tony Ryan, then of GPA and later of Ryanair. A series of articles he published in Magill highlighting the links between the Workers' Party of Ireland and the Official IRA in the 1980s caused him and other journalists to receive death threats. After the publication of "The Lost Revolution: the Story of the Official IRA and the Workers' Party" it was revealed that the Official IRA had planned to assassinate him by planting a bomb on his boat, but the operation was called off at the last minute. He was editor of the Sunday Tribune until 1994. He has written a weekly column for The Irish Times since then, and since 2000, has written weekly for The Sunday Business Post. He started broadcasting on RTÉ radio in 1996.
