Background: Rabbitt was born to Irish immigrants Mae (nee Joyce) and Thomas Michael Rabbitt in Brooklyn, New York in 1941, and was raised in the nearby community of East Orange, New Jersey. His father was an oil-refinery refrigeration worker, and a skilled fiddle and accordion player, who often entertained in local New York City dance halls. By age twelve Rabbitt was a proficient guitar player, having been taught by his scoutmaster, Bob Scwickrath. During his childhood Rabbitt became a self-proclaimed "walking encyclopedia of country music".
Context: Rabbitt was employed as a mental hospital attendant in the late 1950s but, like his father, he fulfilled his love of music by performing at the Six Steps Down club in his hometown. He later won a talent contest and was given an hour of Saturday night radio show time to broadcast a live performance from a bar in Paterson, New Jersey. In 1964, he signed his first record deal with 20th Century Records and released the singles, "Next to the Note" and "Six Nights and Seven Days". Four years later, with $1,000.00 to his name, Rabbitt moved to Nashville where he began his career as a songwriter. During his first night in the town, Rabbitt wrote "Working My Way Up to the Bottom", which Roy Drusky recorded in 1968. To support himself, Rabbitt worked as a truck driver, soda jerk and fruit picker while in Nashville. He was ultimately hired as a staff writer for the Hill & Range Publishing Company and received a salary of $37.50 per week. As a young songwriter, Rabbitt socialized with other aspiring writers at Wally's Clubhouse, a bar in Nashville; he said that he and the other patrons had "no place else to go." Rabbitt became successful as a songwriter in 1969 when Elvis Presley recorded his song "Kentucky Rain". The song went gold and cast Rabbitt as one of Nashville's leading young songwriters. While eating Cap'n Crunch, he penned "Pure Love", which Ronnie Milsap rode to No. 1 in 1974. This song led to a contract offer from Elektra Records. Rabbitt signed with Elektra Records in 1975. His first single under that label, "You Get To Me" made the top 40 that year, and two songs in 1975, "Forgive and Forget" and "I Should Have Married You" nearly made the top 10. These three songs along with a recording of "Pure Love" were included on Rabbitt's self-named debut album in 1975. In 1976 his critically acclaimed Rocky Mountain Music album was released, which handed Rabbitt his first No. 1 country hit with the track "Drinkin' My Baby (Off My Mind)". In 1977 his third album, Rabbitt was released, which made the top 5 on Country Albums chart. Also in 1977 the Academy of Country Music named Rabbitt "Top New Male Vocalist of the Year". By that time he had a good reputation in Nashville, and was being compared by critics to singer Kris Kristofferson. In 1977, at Knott's Berry Farm, Eddie Rabbitt appeared at the CMA and sang several of his songs from the album Rocky Mountain Music. He won the award of Top New Male Vocalist of the Year.
Question: who did he sign with
Answer: 20th Century Records

Problem: Background: Augusta Ada King-Noel, Countess of Lovelace (nee Byron; 10 December 1815 - 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine. As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer. Ada Lovelace was the only legitimate child of the poet Lord Byron, and his wife Anne Isabella "Annabella" Milbanke, Lady Wentworth.
Context: Throughout her illnesses, she continued her education. Her mother's obsession with rooting out any of the insanity of which she accused Byron was one of the reasons that Ada was taught mathematics from an early age. She was privately schooled in mathematics and science by William Frend, William King, and Mary Somerville, the noted researcher and scientific author of the 19th century. One of her later tutors was the mathematician and logician Augustus De Morgan. From 1832, when she was seventeen, her mathematical abilities began to emerge, and her interest in mathematics dominated the majority of her adult life. In a letter to Lady Byron, De Morgan suggested that her daughter's skill in mathematics could lead her to become "an original mathematical investigator, perhaps of first-rate eminence". Lovelace often questioned basic assumptions by integrating poetry and science. While studying differential calculus, she wrote to De Morgan: I may remark that the curious transformations many formulae can undergo, the unsuspected and to a beginner apparently impossible identity of forms exceedingly dissimilar at first sight, is I think one of the chief difficulties in the early part of mathematical studies. I am often reminded of certain sprites and fairies one reads of, who are at one's elbows in one shape now, and the next minute in a form most dissimilar Lovelace believed that intuition and imagination were critical to effectively applying mathematical and scientific concepts. She valued metaphysics as much as mathematics, viewing both as tools for exploring "the unseen worlds around us".

From 1832, when she was seventeen,
