Who is this person?

Agreed, thanks Joe! As for Mme Patti:
On a trip to Chicago in 1853, Mr. Lincoln had heard singer Madame Patti in concert with the Swedish violinist Ole Bull. Later, she was once invited to sing at the White House, obviously shortly after Willie's death. On this website:

...the following is told:
"When the erstwhile child prodigy came to the White House, Mrs. Lincoln told her,'I have wanted to see you; — to see the young girl who has done so much, who has set the whole world talking of her wonderful singing.'" Madame Patti accompanied herself on the piano while singing, 'The Last Rose of Summer.' She realized afterwards that she had "made an awkward choice.' Mary has "risen from her seat and was standing at a window in the back part of the room with her back toward me. I could not see her face but I knew she was weeping." Mr. Lincoln broke the tension by asking for "Home Sweet Home.' Madame Patti's accompanist "did not know the air, and Patti, who knew it, did not know the words, and had never sung them. Seeing her dilemma, 'the President rose from his seat, went quickly to a small stand at the foot of the piano, took from it a small music book, with a vivid green color, and placed it on the piano rack, opened to the music of Home, Sweet Home. Then he returned to his seat without a word and resumed his former posture. 'Well, I sang the song the very best I could do it,' Patti concluded,'and when Mr. Lincoln thanked me his voice was husky and his eyes were full of tears. By that time I was so wrought up over the situation myself that I was actually blubbering when we were taking leave of the recently bereaved parents.'"

Here is a recording of Mme Patti singing "Home Sweet Home", recorded in 1906:

Adelina Patti was the greatest soprano of her day. Born in Madrid to Italian parents on Feb. 19, 1843, Adelina Patti was raised in New York and gave her first concert there at the age of seven. After Patti sang at Covent Garden, London, in 1845, her international career began. As a bel canto coloratura soprano she had no rival. Giuseppe Verdi (BTW, this year, Okt. 10, was his bicentennial!) thought she was the greatest singer he had ever heard.
In the video, you see her castle in the Upper Swansea Valley. She named it "Craig-y-Nos" - "the Rock of Night". There, this and other recordings were made by the Gramophone & Typewriter Co. When she heard her own voice, she commented: "Ah! My God! Now I understand why I am Patti! Yes, what a voice! What an artist! I understand all!" Mme. Patti died at Craig-y-Nos on Sept. 27, 1919.
