Question: John Crout was visited by which physicist to obtain support about xerography?
Context: Chester Floyd Carlson (February 8, 1906 – September 19, 1968) was an American physicist, inventor, and patent attorney born in Seattle, Washington. Xerography or electrophotography is a dry photocopying technique.  Its fundamental principle was invented by Hungarian physicist Pál Selényi and based on Selényi's publications Chester Carlson applied for and was awarded U.S. Patent  on October 6, 1942.  The technique was originally called electrophotography.  It was later renamed xerography—from the Greek roots ξηρός "xeros", "dry" and -γραφία "-graphia", "writing"—to emphasize that, unlike reproduction techniques then in use such as cyanotype, this process used no liquid chemicals. The 1993 confidence motion in the second Major ministry was an explicit confidence motion in the British Conservative Party government of John Major which was proposed in order to ensure support in the British Parliament for the passing of the Maastricht Treaty.  Due to previous defeats caused when Eurosceptic Conservative MPs voted with the opposition, the Government had to obtain support for its policy on the Social Chapter before the European Communities Amendment Act 1993 could come into effect and allow the United Kingdom to ratify the treaty.  Dissenting Conservative MPs were willing to vote against the Government but had to come into line on a confidence motion or else lose the Conservative whip.  Only one eurosceptic MP was deliberately absent and as a result the motion passed by 40 votes and the United Kingdom ratified the Maastricht Treaty. Monthly Abstract Bulletin is a monthly scientific journal documenting recent developments in photographing and printing, published in Rochester, New York from 1915 to 1961.  It is authored by Kodak Research Laboratories, associated with the Anso company, and is published by the Eastman Kodak Company.  It was John H. Dessauer, a former employee of Anco incidentally, who spotted an article about electrostatic photography, later known as xerography in "Monthly Abstract Bulletin" in April 1945 and recognized its potential for copying, who together with Chester Carlson and businessman Joseph C. Wilson were behind the success of the Xerox Corporation. John Shaw Crout (July 5, 1899 - October 31, 1987) was the Director of Engineering at Battelle Memorial Institute when, in 1944, Battelle was visited by Chester Carlson, in order to obtain support for his idea about a xerographic process. John H. Dessauer, also known as Hans Dessauer, (13 May 1905 – 12 August 1993) was a German-American chemical engineer and an innovator in developing xerography.  He was instrumental in turning a $7 million company of the 1930s into Xerox, a billion-dollar copier company. Telephone counseling refers to any type of psychological service performed over the telephone.  Telephone counseling ranges from individual, couple or group psychotherapy with a professional therapist to psychological first aid provided by para-professional counselors.  In-person therapists often advise clients to make use of telephone crisis counseling to provide the client with an avenue to obtain support outside of therapy if they cannot be reached in an emergency or at the conclusion of a thefrapeutic relationship.

The faithful climb up to the temple and obtain Darshan of the shivling and obtain blessings of the Lord.  It is also possible to take an elevator up to the temple.  The temples is visited by lakhs of devotees on annual Mahashivratri festival. Robert W. Gundlach (September 7, 1926 – August 18, 2010) was an American physicist.  He is most noted for his prolific contributions to the field of xerography, specifically the development of the modern photocopier.  Gundlach helped transform the Haloid Company, a small photographic firm, into the thriving Xerox Corporation.  Over the course of his 42 year career with the company, he contributed over 155 patents, making photocopying technology more affordable and practical.  In 1966 Gundlach was named Xerox’s first Research Fellow, the highest non-managerial that could be achieved by a Xerox scientist.  After his retirement in 1995, he was granted several patents associated with his hobbies, including a snow-making system and a special backpack. Recreational drug tourism is travel for the purpose of obtaining or using drugs for recreational use that are unavailable, illegal or very expensive in one's home jurisdiction.  A drug tourist may cross a national border to obtain a drug that is not sold in one's home country, or to obtain an illegal drug that is more available in the visited destination.  A drug tourist may also cross a sub-national border (from one province/county/state to another) in order to purchase alcohol or tobacco more easily, or at a lower price due to tax laws or other regulations.
