A roundup of notable gifts compiled by The Chronicle:
Brian Acton, the billionaire co-founder of the messaging program WhatsApp, has donated $50 million to this new nonprofit organization, which makes an encrypted messaging app promising surveillance-free communication.
The goal of the effort is to make “private communication accessible and ubiquitous,” the foundation stated.
Mr. Acton and his business partner sold WhatsApp to Facebook for $19 billion in 2014. He has also joined the charity as its executive chairman.
Hammer Museum at U. of California at Los Angeles
Lynda and Stewart Resnick have given $30 million to the Los Angeles museum’s capital campaign. The Resnicks own the Wonderful Company, which operates a variety of food and beverage brands like Fiji Water, Pom Wonderful, and Wonderful Pistachios. In honor of the gift, the museum will name its building the Lynda and Stewart Resnick Cultural Center.
The museum’s capital campaign also received $20 million from Marcy Carsey, a partner at the Carsey-Werner Company, which produced a number of hit television programs including The Cosby Show, Roseanne, and That ‘70s Show. She has served as the museum’s board chair since 2014.
Richard Chaifetz and his wife, Jill, gave $15 million for the right to rename its business school and support a center for entrepreneurship.
Mr. Chaifetz is the founder and chairman of ComPsych, a Chicago company that provides products and services to companies to help their employees with personal matters. He is also founder and chairman of the Chaifetz Group, a venture-capital firm. This is the second major contribution the couple has made to the university, following a $12 million gift in 2007 for its sports arena.
Since 2000, the business school has been named for John Cook, who gave an undisclosed gift for the naming rights in that year. The university says Mr. Cook agreed to give up his naming rights if it helped the institution reach its fundraising goals.

The university has received $12 million from Roger, Fran, Paul, and Elke Koch to create the Koch Center for Family Business and two endowed professorships that will educate students who inherit or work at family businesses.

The performing-arts group has received a $1.8 million bequest from Linda Garner Riggs for its education programs and to attract outstanding professional musicians to the symphony. She retired as a managing director of the investment banking firm at Stephens, in Little Rock, Ark.
