NEW YORK—The funeral for Bank of America CEO David Kessler, intended as a solemn remembrance of the 73-year-old's life, quickly developed into a networking dream for executives who attended the service at Beth Israel Synagogue Tuesday. "This [funeral] couldn't have come at a more perfect time for me," said public relations executive Sarah Freeman. "All the biggies were there—Intel, McDonald's, Citigroup, Nike. I've collected about 25 business cards in the last hour alone, handed out dozens more." Freeman added that although she wasn't initially planning on attending the burial, she cleared her afternoon schedule when she found out Viacom CEO Philippe Dauman would be in attendance.
