William F. Ludwig Jr ( 1916 - 2008)  in Chicago, Illinois, to William Ludwig, Sr. and Elsa Maria Gunkler. William Jr. played percussion throughout his grade school years and at the age of 16 won the National Solo Drum Competition. After graduating from Park-River Forest High School in Oak Park, Illinois, he went on to attend the University of Illinois. There he enrolled in the School of Business Economics and served as solo timpanist with the University of Illinois Concert Band as well as playing drums on weekends making $ 4.00 a night.

Around 1937, just eight years after the Ludwig & Ludwig Drum Company had been sold to Conn, William Ludwig, Jr. co-founded, along with his father Ludwig Sr., the W.F.L. Drum Company in Chicago. William Jr. became the Sales and Advertising manager for the W.F.L. Drum Company, designing his first Ludwig catalog in 1939 known as “Big Red” because it had a red cover. His second catalog was the 1940 catalog with a green cover. Both had Ray Bauduc of Dixieland fame on the cover.

In May of 1942, Ludwig Jr. was drafted into the Navy and went to the Great Lakes Naval Training Station in North Chicago. He was welcomed by an old Ludwig & Ludwig banjo artist, Lt. Eddie Peabody. PeabodyPeabody utilized Ludwig’s skill to train drummers in the art of military drumming. Thousands of soldiers, in 12 drum corps, learned to march to the beat of drummers trained by Ludwig, who reached the rank of Chief Petty Officer. had been chastised by an Admiral for the poor marching habits of their recruits. For the next three years,

After completing his service in 1945, Ludwig Jr. returned to WFL Drum Company. He designed the 1947 WFL drum catalog which contained the new Classic line of lug casings and had a picture of Buddy Rich on the front cover.

In 1955 Conn exited the drum business and sold the Ludwig name back to the Ludwig family. Under William junior’s guidance, the Ludwig Drum Company once again became the world’s largest drum company.

A milestone in the company history came in 1964 when the Beatles appeared on the Ed Sullivan Show with Ludwig drums. The resulting demand for Ludwig drums forced the family to add a night shift at the manufacturing plant.

In 1970, William F. Ludwig II became President of the Ludwig Drum Company. The 1980 Ludwig catalog was the last Ludwig catalog written by Mr. Ludwig.

Ludwig Industries was sold to Selmer in 1981 and manufacturing was moved three years later to Monroe, North Carolina. Wm. F. Ludwig II worked as a consultant for the firm, and in his retirement spent more time perfecting his lecture/demonstration "A History of Drumming in America". The presentation included a demonstration of the sound effect devices used by theater drummers … and in his demo, Ludwig II utilized the effects actually used in theater drumming by his father, Ludwig Senior. In recognition of his educational efforts and general contributions to the arts, Capital University in 1987 awarded Ludwig an honorary Doctorate of Humanities degree.

In his retirement, Ludwig demonstrated how integral a part of the percussion world he really was. He auditioned annually for the Wheaton Community Orchestra, earning the tympani chair year after year and played timpani at his church each Easter Sunday.

Though he no longer had a vested interest in the drum company, Ludwig for decades acted as a goodwill ambassador. He appeared regularly at major industry events such as the Chicago Drum Show and Percussive Arts Society conventions. In 1993 PAS inducted him to the Percussive Arts Society Hall of Fame. His father was already a member, having been inducted in 1972. Other than the Zildjian, they are the only father-son members of this elite group.

In 2001, Ludwig penned his autobiography, The Making Of A Drum Company, published by Rebeats Publications. He produced the first drafts of his book using the manual typewriter he’d used for his correspondence for over 50 years.

On March 22, 2008, at the age of 91, William F. Ludwig II died in Chicago of natural causes. He is survived by his son William F. Ludwig III of Chicago and daughter Brooke Crowden of Irving, TX.

William F. Ludwig II was recognized as a leading authority in the manufacturing of all types of percussion instruments. A guardian of the Ludwig family heritage, William F. Ludwig II had an extensive museum of early drums dating from the Revolutionary War, plus collected and cataloged every American drum and accessory patent ever issued by the United States Patent Office, beginning with the Zimmerman percussion patent of 1858.
