••• “Katy Perry might be too bouncy for ‘Sesame Street,’ but she’ll be happy on North Moore Street. Perry and fiancé Russell Brand have just closed on a two-bedroom, two-bathroom penthouse for $2.7 million, reports The Post’s Andy Wang. The condo, with a south-facing terrace, is—surprisingly for stars who recently tangled with paparazzi—in a nondoorman building.

••• “He couldn’t go to medical school in New York, so James McCune Smith went to Scotland for his degree and returned home to treat the city’s poor. The degree he earned in 1837 made him the nation’s first professionally trained African-American doctor. He set up a medical practice in lower Manhattan [Tribeca, the article later says] and became the resident physician at an orphanage. Celebrated during his lifetime as a teacher, writer and anti-slavery leader, Smith fell into obscurity after his death in 1865 and was buried in an unmarked grave. On Sunday, descendants who only recently learned they had a black ancestor, will honor Smith at his Brooklyn grave. It will be marked with a new tombstone.” (AP)
