A reclusive member of the wealthy Rothschild dynasty is believed to have died after his Los Angeles home suddenly caught fire.

Firefighters discovered the body of a man in the Hollywood Hills home after they were called to fight the blaze just after 4:30 p.m. Wednesday, the Los Angeles Fire Department said.

Authorities have not yet released the man’s name, but several neighbors identified him as William Rothschild – a member of the prominent banking family, ABC7 reported.

Neighbors said Rothschild, who was in his late 70s, lived in the two-bedroom home with his Afghan dog.

They described him as a reclusive and eccentric millionaire who owned several properties on the same street and a slew of expensive vintage cars, the newspaper said.

“It’s very sad,” said Jim Moore, who lives nearby. “He was a good guy. A good neighbor.”

Some neighbors said they had never seen the reclusive Rothschild and assumed the property was empty.

The Rothschild family built their fortune by establishing banks across Europe beginning in the late 18th century.

They have an estimated net worth of around $1 billion.

The burned-out, 825-square-foot home was estimated to be worth about $1 million, real estate listings show.

It was not immediately clear what started the fire and authorities said the incident was still under investigation.

It took 45 firefighters about 30 minutes to extinguish the flames.

The Los Angeles County coroner will formally identify the man and determine his cause of death, authorities said.
