Amid a staggering tide of Sept. 11-related DVDs and press releases as the 10th anniversary nears, one particularly worthwhile event stood out while sifting through my post-vacation inbox.

On Sept. 24, the Kaplan Stahler Agency is underwritng the 13th annual Tennis for Tots event at the Los Angeles Tennis Club, honoring the memory of “Frasier” producer David Angell and his wife, Lynn, who were among the passengers who died when the first plane struck the World Trade Center on Sept. 11.

Principal Mitch Kaplan noted that the agency began sponsoring the event before 2001, but switched it to the David & Lynn Angell Memorial as a tribute to the Angells, who were also active in children’s charities. (A total of $850,000 has been raised for the beneficiary, the Alliance for Children’s Rights, and the goal is to push that total over $1 million this year. Additional info is available via the group’s website.)

Among the event’s sponsors are Angell’s producing partners Peter Casey and David Lee, who — in one of those footnotes I can’t resist — credited Angell with coining the term “boinking” as a euphemism for sex while they were working on “Cheers.”

At the time of his death, Casey and Lee stated, “David Angell was not only our partner but also our friend for the past 16 years. He was a kind and gentle man with a quiet exterior that masked one of the sharpest comedy minds ever to write for television.”

Angell, who was 55 when he died, was posthumously honored by the Writers Guild of America with its Valentine Davies Award.
