Michael H. Kean was reintroduced to Sherlock Holmes while in graduate school, when his girlfriend, (Connie, now his wife of many years), gave him a copy of the complete Canon as a birthday gift. As his career took him westward, from Philadelphia, to Chicago, to California's Monterey Peninsula, he became a member of the Sons of the Copper Beeches, the Hounds of the Baskerville (
sic), and the Diogenes Club of Carmel-by-the-Sea. He was invested in the Baker Street Irregulars in 1979 as General Charles Gordon. A retired publishing executive, he served as Co-Publisher of the BSI Press and received the Two-Shilling Award in 2013. He was named the BSI's "Cartwright" in 2016, and in 2020 he became the sixth person to lead the Baker Street Irregulars, succeeding Mike Whelan as "Wiggins."
The study of the lives of Mr. Sherlock Holmes and John H. Watson, M.D., has been Mr. Klinger's consuming passion since 1994. He has published numerous articles on Sherlockiana and a number of books, among them

Richard M. Olken, BSI (" Bob Carruthers," 2006) has loved Sherlock Holmes for as long as he has loved bicycles (and bicycles were his father's family business). A graduate of Harvard University and Boston University School of Law, Richard became the Executive Director and Congressional lobbyist for the BikesBelong Coalition. He was also the Dean of the School of Bartending at Harvard University. Now retired, he has served as Poker for the Speckled Band of Boston since 1995 and is a member of many other Sherlockian societies worldwide.

Marsha Pollak has been an avid mystery reader since her childhood when she devoured the complete sets of Judy Bolton and Nancy Drew adventures. As a librarian, her career took her to Buffalo N.Y. where she was present for the founding of her first Scion, An Irish Secret Society at Buffalo, and became a member of The Adventuresses of Sherlock Holmes (Mrs. Neville St. Clair). Holmes has stayed in her life as she moved and made more friends in societies in Florida, Texas and, for the last 27 years, California. She became a member of The Baker Street Irregulars in 1996 ("A Small But Select Library") and now leads the Oral History Project. She is also the Chairman of The Sub-Librarians Scion of the Baker Street Irregulars in the American Library Association, the oldest profession-oriented group interested in Sherlock Holmes.

Dan Posnansky has been a student of The Canon since he could read and he became a "connoisseur" of fine books not long after that. He is remarkably generous with his time and knowledge of The Canon, books and U.S. publishing history, with collectors and libraries.
Dan is a longtime member of The Speckled Band of Boston, where he has served as The Keeper of the Band. Dan is also a most active member of The Baker Street Irregulars ("Colonel Hayter," 1977) and a founder of The Friends of Irene Adler.

Constantine Rossakis has been a devout Sherlockian since the sixth grade, when he wrote a report on "The Greek Interpreter." His passion for matters bibliophilic as well as Sherlock Holmes continued to evolve since then, and he began to build his Sherlockian library almost twenty years ago, emphasizing first editions, first appearances, and manuscript material. He is the author of numerous medical and Sherlockian articles, lectured at the inaugural meeting of Mycroft's League in Philadelphia, and is a member of The Grolier Club. Costa received his investiture into The Baker Street Irregulars in 2004 as "St. Bartholomew's Hospital," and was the recipient of The Morley-Montgomery Memorial Award for
The Baker Street Journal outstanding article in 2004. He will be editor of The BSI Manuscript Series for 2008. Costa remains in private practice as an interventional and consultative Cardiologist in Bergen County, New Jersey, to offset the cost of his expanding family and collection.
Steven Rothman discovered that at heart he was a Sherlockian when he read with great amusement Baring-Gould's Sherlock Holmes of Baker Street. Thus vaccinated by canonical scholarship at the tender age of 12, he was destined to become an Irregular. He soon discovered that his other love in literature, Christopher Morley, was entwined with the BSI. In 1990 he edited
The Standard Doyle Company: Christopher Morley on Sherlock Holmes (Fordham University Press). Rothman's long association with the BSI ("The Valley of Fear," 1986) includes editorship of
The Baker Street Journal since 2000.
In 1950, Michael Whelan purchased
The Complete Sherlock Holmes, Garden City edition with his caddy tips. Neither he nor his mother who had sparked his interest in Sherlock Holmes, had an inkling of where that particular purchase would lead him. That passion, thus ignited, has continued unabated for over 50 years. Sherlockian zeal, wrapped as close as an Inverness cape, has accompanied him from coast to coast and around the world. Whelan led the Baker Street Irregulars as "Wiggins" for 23 years and is now "Wiggins
Emeritus." He is a retired business executive, married to Mary Ann Bradley [honoured as "
The Woman" of The BSI (1993) and invested as "Mary Morstan" (2012)], with three sons and six grandchildren. He is also currently the Board president of The Friends of the Lilly Library and a member of the Indianapolis Literary Club, as well as a proud member of several Sherlockian societies..
