Frank Boos, 70; Was Appraiser on PBS’ ‘Antiques Roadshow’

Frank Boos, 70, the bow-tied appraiser on the PBS television program “Antiques Roadshow,” died Tuesday at his home in Bloomfield Hills, Mich., of complications from vascular disease, according to his son, Jonathan.

Boos, an original member of the show’s cast, appraised thousands of antiques, mainly silver, as the show toured various American cities.

“He really maintained -- up until the very last time we worked with him -- genuine, childlike excitement about the old things,” said Marsha Bemko, executive producer of “Antiques Roadshow,” which is produced by WGBH-TV in Boston.

Boos ran an auction, appraisal and gallery business in Troy, Mich., for 37 years, at times handling the sale of leading art collections.

He also handled the collection of the late Minoru and Teruko Yamasaki. Minoru Yamasaki designed the World Trade Center towers in New York City.

Born in Detroit, Boos grew up in Grosse Pointe Farms and graduated with a degree in history from Trinity College in Hartford, Conn., in 1957.

He had a collection of several hundred bow ties, his son told the Detroit Free Press.

“The larger and crazier the pattern, the better he liked them,” Jonathan Boos said. “He didn’t own many conservative ties.”
