Janner continued to attend the House of Lords until December 2013. He was on leave of absence from the House of Lords from 13 October 2014. Janner wrote a number of books on public speaking and business communication, including "On Presentation". In addition, he wrote extensively under the pen-name Ewan Mitchell. He was a former member of The Magic Circle and the International Brotherhood of Magicians. In 1955, Janner married Myra Louise Sheink, who was originally from Australia and the niece of Sir Israel Brodie, the former Chief Rabbi of Great Britain and the Commonwealth. The couple had three children: two daughters and a son. Myra Sheink died in 1996. Lord Janner's younger daughter is Rabbi Laura Janner-Klausner, who was appointed Senior Rabbi to Reform Judaism in 2011. She is married to a brother of the Israeli writer Amos Oz. Marion Janner, his other daughter, was appointed Officer of the Order of the British Empire (OBE) for services to mental health in 2010. Daniel Janner, his son, is a barrister and QC. In 2009, Janner was diagnosed with Alzheimer's disease. Its advancing severity meant that by 2015 he required round-the-clock care for his dementia. At a court hearing in August 2015, a medical specialist acting as a witness for the defence said that Janner was experiencing the early stages of Parkinson's disease. Janner died on 19 December 2015 from complications of Alzheimer's disease, aged 87. Over the years, starting in 1991, specific allegations of sex abuse of children by Janner in the past—dating ultimately from at least 1955—were made to authorities. This did not lead to any official action, beyond Janner being questioned once, from the first allegations until 2015. After it was decided in 2015 that he should have been prosecuted earlier, the accusations were to be investigated in a "trial of the facts" in April 2016—Janner was deemed to be too ill for a criminal trial—but he died before this could happen, though his actions were included in a large inquiry into historical sex abuse. In 1991, the director of a children's home in Leicestershire, Frank Beck, was convicted of child abuse over 13 years to 1986 and sentenced to five life terms. During the trial, Beck accused Janner of having abused a child, and a witness said that while he was in care Janner had abused him. Janner could not say that Beck was lying until after the trial, because it would have been in contempt of court.
