Montague Marsden Glass (1877 - 1934) was a British-American Jewish lawyer and writer of short stories, plays and film scripts. His greatest success came with the creation of his fictional duo Abe Potash and Mawrus Perlmutter, who appeared in three books, a play and several films. Glass was born in Manchester, England, but spent his childhood in Baguley, in Cheshire. Glass' father worked in the linen and cotton trade. The Glass family moved to New York in 1890, in pursuit of Glass' father's business interests. Glass married Mary Caroline Patterson in 1908. He attended The College of the City of New York and New York University Law School. After qualifying for the bar, Glass practiced law for several years while writing semi-professionally on the side. In 1909, Glass abandoned the practice of law to write full-time. Glass' transition from law to professional writing coincided with the emergence of the a pair of characters that would prove to be his most enduringly popular creations: Abe Potash and Mawrus Perlmutter.
