Example Input: Passage: Joséphine-Éléonore-Marie-Pauline de Galard de Brassac de Béarn (1825–1860) married Albert de Broglie on 18 June 1845, and they had five sons together. Although not high royalty, on the occasion of their marriage, they styled themselves Prince and Princesse respectively. Pauline was a highly intelligent and religious woman, who was well read and wrote a number of texts in her lifetime. Her shyness was well known; she was widely considered strikingly beautiful and charming, but those around her would often avoid eye contact so as not to embarrass her. Albert was devoted to his wife, and commissioned the painting after being impressed by Ingres' 1845 portrait of his sister, the Comtesse d'Haussonville.
Albert approached Ingres around 1850 to undertake the portrait. Ingres dined with the de Broglie family in January 1850, and according to one eye witness, "seemed to be very happy with his model."Although Ingres' main source of income came from portraiture, it distracted from his main interest in history painting, which early in his career, was far less lucrative. He found acclaim in the 1840s, when he became successful enough to no longer depend on commissions. This painting was Ingres' second-last female portrait, and final society portrait.Influenced by the working methods of Jacques-Louis David, Ingres began with a number of nude preparatory sketches, for which he employed professional models. He built up a picture of the sitter's underlying anatomical structure, as seen in the Musée Bonnat study, before deciding on how to build the lavish costume and accessories. Although there is no surviving record of the commissions, and the exact sequence of events is uncertain, the sketches can be dated from 1850, the year the style of her evening dress came into fashion. Ingres signed and dated the final picture at the left center "J. INGRES. pit 1853".Pauline died in 1860 aged 35 from tuberculosis. After her death, Albert published three volumes of her essays on religious history. Albert (who in 1873 became the 28th Prime Minister of France) lived until 1901, but was heartbroken and did not remarry. He kept her portrait for the remainder of his life draped in fabric and hidden behind a velvet curtain, only lending it to select exhibitions. After his own death, the painting passed within the family until 1958 when it was sold to the Metropolitan Museum of Art via the banker and art collector Robert Lehman, and is today held in the Lehman Wing. The family kept most of the jewelry and accessories seen in the painting, although the marabou feathers were sold to the Costume Institute of the Metropolitan Museum. 
Question: What is the full name of the person who bought the portrait of the wife of the man who was heartbroken and did not remarry?
Example Output: Robert Lehman.

Example Input: Passage: Louis Salinger, an Interpol detective, and Eleanor Whitman, an Assistant District Attorney from Manhattan, are investigating the International Bank of Business and Credit, which funds activities such as money laundering, terrorism, arms trading, and the destabilization of governments. Salinger's and Whitman's investigation takes them from Berlin to Milan, where the IBBC assassinates Umberto Calvini, an arms manufacturer who is an Italian prime ministerial candidate. The bank's assassin diverts suspicion to a local assassin with political connections, who is promptly killed by a corrupt policeman. Salinger and Whitman get a lead on the second assassin, but the corrupt policeman shows up again and orders them out of the country. At the airport they are able to check the security camera footage for clues on the whereabouts on the bank's assassin, and follow a suspect to New York City.
In New York, Salinger and Whitman are met by two New York Police Department detectives, Iggy Ornelas and Bernie Ward, who have a photograph of the assassin's face when he arrived in New York airport. Salinger, Ornelas, and Ward locate Dr. Isaacson to whose practice the assassin's leg brace has been traced. They find the assassin and follow him to the Solomon R. Guggenheim Museum.
Jonas Skarssen, the chairman of the IBBC, reveals to his senior men White and Wexler that the bank had Calvini killed so that they could deal with his sons to buy missile guidance systems in which the bank has invested. Since the bank knows that Salinger and Whitman are close to finding their assassin, they send a hit team to kill him at a meeting between him and his handler, Wexler. Wexler leaves and is arrested by Ornelas. As Salinger speaks to the assassin, a shootout at the Guggenheim erupts when a number of gunmen attempt to kill them with automatic weapons. They escape, but the assassin is mortally wounded. 
Question: What are the first names of the people who locate Dr. Isaacson?
Example Output: Louis.
