input: Please answer the following: A friend asked me to answer this question: What is the last name of the person who contributed to albums and hit singles as a producer?, using the article: Steven Lee Lukather (born October 21, 1957) is an American guitarist, singer, songwriter, arranger and record producer, best known as a founding member of Toto. A prolific session musician, Lukather has recorded guitar tracks for more than 1,500 albums representing a broad array of artists and genres. He has also contributed to albums and hit singles as a songwriter, arranger and producer. Lukather was a prominent contributor to several studio albums by Michael Jackson, including Thriller, the best-selling album of all time. Lukather has released seven solo albums, the latest of which, Transition, was released in January 2013. In 1976, when Lukather was nineteen years old, he was invited by his high school friends David Paich and the Porcaro brothers Steve and Jeff to join them in forming their band, Toto. He has been a member of the band ever since it began, and is still fully contributing to their album composition and touring. Lukather's reputation as a guitarist and his association with Paich and the Porcaro brothers, who also became established artists, allowed him to secure a steady flow of session work in the 1970s and 1980s. Lukather has been nominated for twelve Grammy Awards, and has won five. While his work with Toto was predominantly based on pop rock music and his solo work ventures into progressive rock and hard rock, many of Lukather's side-projects are focused on jazz fusion. He held a long-time collaboration with jazz guitarist Larry Carlton that produced a Grammy-winning live album, and he was a member of the jazz fusion band Los Lobotomys, a collaboration of notable session musicians.

Problem: A friend asked me to answer this question: What is the first name of the person who was was able to brief Vannevar Bush after he returned to the US?, using the article: The MAUD Committee reports urged the co-operation with the United States should be continued in the research of nuclear fission. Charles C. Lauritsen, a Caltech physicist working at the National Defense Research Committee (NDRC), was in London during this time and was invited to sit in on a MAUD meeting. The committee pushed for rapid development of nuclear weapons using gaseous-diffusion as their isotope separation device. Once he returned to the United States, he was able to brief Vannevar Bush, the director of the Office of Scientific Research and Development (OSRD), concerning the details discussed during the meeting.In August 1941, Mark Oliphant, the director of the physics department at the University of Birmingham and an original member of the MAUD Committee, was sent to the US to assist the NDRC on radar. During his visit he met with William D. Coolidge. Coolidge was shocked when Oliphant informed him that the British had predicted that only ten kilograms of uranium-235 would be sufficient to supply a chain reaction effected by fast moving neutrons. While in America, Oliphant discovered that the chairman of the OSRD S-1 Section, Lyman Briggs, had locked away the MAUD reports transferred from Britain entailing the initial discoveries and had not informed the S-1 Committee members of all its findings.Oliphant took the initiative himself to enlighten the scientific community in the U.S. of the recent ground breaking discoveries the MAUD Committee had just exposed. Oliphant also travelled to Berkley to meet with Ernest Lawrence, inventor of the cyclotron. After Oliphant informed Lawrence of his report on uranium, Lawrence met with NDRC chairman James Bryant Conant, George B. Pegram, and Arthur Compton to relay the details which Oliphant had directed to Lawrence. Oliphant was not only able to get in touch with Lawrence, but he met with Conant and Bush to inform them of the significant data the MAUD had discovered. Oliphant's ability to inform the Americans led to Oliphant convincing Lawrence, Lawrence..., what would be the answer ?
