The element berkelium is named after the city of Berkeley, California.
Berkelium was first produced in December 1949 by Stanley Thompson, Albert Ghiorso, and Glenn Seaborg in the 60-inch cyclotron housed at the University of California at Berkeley’s Crocker Laboratory. They bombarded americium-241 with helium nuclei (alpha particles) for several hours in the cyclotron to synthesize tiny amounts of the radioactive metallic element.
The Crocker Laboratory was demolished in the 1960s to make way for new UC Berkeley campus buildings, and was situated where Tan Hall and Pimentel Hall stand today.
There are open air parking lots surrounding North Berkeley BART station.

Parking permits should be booked online in advance and the daily parking fee can be paid at the Addfare / Parking Validation machine in the station using your stall number.
Swimming is allowed at Lake Anza in Berkeley’s Tilden Regional Park in the designated beach area on weekends and holidays from around the end of April and on weekdays from the end of May until around mid-September. Swimming is prohibited from November onwards and when periods of poor water quality are identified by East Bay Regional Park District. When lifeguards are on duty during swim season, a beach access fee is charged.
The fifth-floor balcony of Unit 405 at 2020 Kittredge Street in downtown Berkeley collapsed in the early hours of June 16th, 2015, and a group of people standing on it fell to the street below. Five Irish students and an Irish-American citizen, all in their early 20s, died and seven others were injured in the incident. Dry rot was a contributing factor in the structural failure, and balconies have since been removed from the building.
