Question: Question: Was the Social Democratic Party around when Knochel was conscripted into the Imperial Army? Passage:Wilhelm Knöchel was born into a Social Democratic working class family in Offenbach, a short distance upriver from Frankfurt. He qualified and worked as a factory machine operator ("Dreher"). In 1917 he was conscripted into the Imperial Army, shortly after which he was badly wounded. There are also references to his having worked as a mines maintenance engineer ("Grubenschlosser"). In 1919, with Germany affected by acute economic hardship and, especially in the cities, a succession of revolutionary uprisings, Knöchel joined the Social Democratic Party ("Sozialdemokratische Partei Deutschlands" / SPD). By 1920 he had relocated in search of work to the industrially vital and internationally critical Ruhr region. Sources differ over whether it was in 1920 or 1923 that he switched to the recently created Communist Party. Between 1924 and 1930 he was a member of the party leadership team for the Dortmund region ("...des Unterbezirk Dortmund"). In 1930, following the death of his first wife, he returned to Offenbach, where it was arranged that his daughter should be brought up by relatives. Knöchel was now employed as a party official.

Passage:The manor is recorded in the Domesday Book where it is listed as Holehale, one of the lands of Robert de Stafford. "In Ferncombe Hundred in Holehale (Ullenhall) 1 hide. Land for 15 ploughs. 17 villagers and 11 smallholders with 6 ploughs. Woodland ½ league long and 1 furlong wide. The value was and is £3 Waga held it." Waga, whose name is preserved in the nearby village of Wootton Wawen, was one of the witness's to Earl Leofric's, husband of Lady Godiva, foundation of the monastery at Coventry during the first year of the reign of Edward the Confessor (1042/3). His lands extended beyond those at Ullenhall, but, following the Conquest, Ullenhall was bestowed by the conqueror on Robert de Stafford, descended from the de Tonei family and who had fought stoutly with Duke William against King Harold. He made Stafford his principal seat, where he had a strong castle and assumed his surname from thence.

Question: Question: Which city was larger at the time Berk was moved to the Lubbock campus, Odessa or El Paso? Passage:At the time of his ordeal, Berk was the regional dean of the Texas Tech medical branch in Amarillo, but on August 1, 2006, he was moved to the high position at the Lubbock campus. There are two other branch campuses in Odessa and El Paso. At the time of his abduction, Berk was at home on Sunday morning with his younger son, Justin. The older son, Jeremy, was away in college. Berk's wife, Shirley H. Berk (born c. 1950), a microbiologist who had served on a school board while they lived in Johnson City, Tennessee, was at church. The culprit, Jack Lindsey Jordan (born in 1963 in Seminole, Texas), gained entry from an open rear garage door and an unlocked back entrance to the residence. Normally, both the garage and the back door would have been locked. Jordan demanded money and jewelry to pay for transportation and narcotics, particularly methamphetamines, as he proceeded along Interstate 40 west toward New Mexico. After being held for four hours in Jordan's vehicle on a cool, windy day, common to the Panhandle in March, Berk was released unharmed near a gasoline station in rural Bushland in southwestern Potter County. This life-threatening event propelled the physician to write about his ordeal. He interlaces the narrative with much of his life story, from his birth in New York City, his childhood in New Jersey, his medical education at Boston University School of Medicine, his work in the fields of infectious diseases,geriatrics, and internal medicine at the East Tennessee State University James H. Quillen College of Medicine in Johnson City, and his relocation to Amarillo, his adopted city which he had grown to love. Since the events of 2005, Dr. Berk has been transferred to the main medical campus in Lubbock.
