The Huntington Library, Art Collections and Botanical Gardens in San Marino on Thursday announced a $32 million gift from Los Angeles billionaire Charles Munger toward building a new education and visitor center.

Munger’s gift is the lead donation to the $60 million project, Huntington officials said. Construction has already begun on the project, which will include 6.5 acres of new gardens and a 43,000 square-foot building with 400-seat lecture hall, classrooms, gift shop and an underground storage complex for museum holdings. The center is expected to be completed in early 2015.

The Munger family previously gave money for the Huntington’s Munger Research Center, which opened in 2004.

In the Business Journal’s latest survey of the 50 Wealthiest Angelenos, Charles Munger ranked 31st, with an estimated net worth of $1.41 billion. He is best known for his role as Warren Buffett’s right-hand man and serves as vice chairman of Omaha, Neb. conglomerate Berkshire Hathaway.
