Lieutenant James Tragg, the stern yet professionally respectful Los Angeles district attorney investigator, was portrayed by actor William Hopper (1915–1970) across the CBS Perry Mason television series from 1957 to 1966. Hopper, the son of Hollywood legend Warner Baxter, brought a clipped, methodical presence to the role, appearing in dozens of episodes as Mason’s recurring prosecutorial counterpart. This evergreen profile explains who played Lieutenant Tragg, details his function within the show’s trial structures, lists notable cases, and contextualizes Hopper’s career and legacy within the series.
Who Played Lieutenant Tragg and Basic Role Context
William Hopper assumed the role of Lieutenant Tragg throughout the long-running black-and-white and early color Perry Mason series. As a lieutenant in the Los Angeles district attorney’s office, Tragg typically led the investigative effort against Mason’s clients, serving as the principal foil during prosecutorial phases of each episode. The character was written as diligent, by-the-book, and occasionally skeptical of Mason’s unorthodox methods, while still adhering to professional norms expected of a midcentury homicide and trial prosecutor unit.
Actor Background: William Hopper
William Hopper, born January 26, 1915, in Los Angeles, was the son of silent-film star Warner Baxter. Before Perry Mason, he built a steady film and television career spanning the 1940s through the 1960s. His casting as Tragg emphasized a restrained, procedural style that contrasted with Perry Mason’s dramatic courtroom flourishes. Hopper’s offscreen health issues, including a long recovery from a 1950s accident, influenced the pacing and frequency of Tragg’s appearances but did not diminish the character’s narrative weight across the series’ run.
Function Within the Perry Mason Formula
Within each episode, Lieutenant Tragg typically functioned as the investigative lead who gathered evidence, interviewed witnesses, and coordinated with the district attorney’s office. His interactions with Mason were often adversarial yet rule-bound, highlighting the system through which Mason frequently found procedural flaws. Tragg’s presence reinforced the procedural legitimacy of Mason’s courtroom victories, anchoring the show’s drama in the realities of police work and prosecutorial process during the late 1950s and early 1960s.

Episode Count and Consistency
William Hopper appeared in a substantial subset of Perry Mason episodes, though Tragg was not present in every installment. His consistent involvement in high-stakes trials underscored the character’s importance to the series’ procedural credibility. Production schedules, Hopper’s health, and narrative focus sometimes shifted Tragg to the background, yet his role remained an identifiable constant across the show’s run.
Comparisons with Other DA Investigators on the Show
Within the Perry Mason universe, Tragg operated alongside district attorney Hamilton Burger and various assistants, but he remained the primary field investigator. Compared with supporting DAs and assistants who occasionally appeared, Tragg’s responsibilities were broader and more central to evidence gathering. This distinction clarified his function as the bridge between police work and courtroom strategy, differentiating him from purely administrative or courtroom-focused figures.
Contrast with District Attorney Burger
While District Attorney Burger handled courtroom decisions and legal strategy, Lieutenant Tragg focused on external evidence collection and witness interviews. The two maintained a cooperative, if occasionally tense, working relationship. This separation of duties allowed Mason to exploit investigative gaps without undermining the show’s depiction of prosecutorial integrity.
