The Royal Institution Christmas Lectures are a series of lectures on a single topic each, which have been held at the Royal Institution in London each year since 1825, missing 1939–1942 because of the Second World War. The lectures present scientific subjects to a general audience, including young people, in an informative and entertaining manner. Michael Faraday initiated the Christmas Lecture series in 1825, at a time when organised education for young people was scarce. Faraday presented nineteen series of lectures in all. History The Royal Institution's Christmas Lectures were first held in 1825, and have continued on an annual basis since then except for four years during the Second World War. They have been hosted each year at the Royal Institution itself, except in 1929 and between 2005 and 2006, each time due to refurbishment of the building. They were created by Michael Faraday, who later hosted the lecture season on nineteen occasions. The Nobel laureate Sir William Bragg gave the Christmas lectures on four occasions, and his co-laureate son Sir Lawrence Bragg gave them twice. Other notable lecturers have included Desmond Morris (1964), Eric Laithwaite (1966 & 1974), Sir George Porter (1969 & 1976), Sir David Attenborough (1973), Heinz Wolff (1975), Carl Sagan (1977), Richard Dawkins (1991), Baroness Susan Greenfield (1994), Dame Nancy Rothwell (1998), Monica Grady (2003), Sue Hartley (2009), Alison Woollard (2013), Danielle George (2014), and Saiful Islam (2016). The props for the lectures are designed and created by the RI's science demonstration technician, a post which Faraday previously held. A popular technician, with the advent of television, serving from 1948 to 1986, was Bill Coates. The technician is informed of the general subject of the lectures during spring, but the specifics aren't settled until September, with the recordings made in mid-December. By 2009, the lectures had expanded to a series of five sessions each year. However, in 2010 the Royal Institution cut back on costs as it had become over £2 million in debt. These cost-cutting measures included the budget allotted to the Christmas Lectures. This resulted in a reduction from five sessions to three. Television A single Christmas Lecture, by G. I. Taylor, was the first to be televised, in 1936, on the BBC's fledgling Television Service. They were broadcast on BBC Two from 1966 to 1999 and Channel 4 from 2000 to 2004. In 2000 one of the lectures was broadcast live for
