Judy Drucker, a South Florida impresario who for decades brought the stars of concert music, opera and dance to Miami, elevating the city’s cultural scene with inexhaustible enthusiasm and self-confidence, died on March 30 at a care facility in Miami. She was 91.

Her daughter Vicki Schwartz said the cause was complications of Alzheimer’s disease.

From the late-1960s until about a decade ago, Ms. Drucker presented a panoply of talented artists to the Miami area. The list includes Beverly Sills, Isaac Stern, Vladimir Horowitz, Yo Yo Ma, Leonard Bernstein, Mikhail Baryshnikov, Richard Tucker, Twyla Tharp, Zubin Mehta, Pinchas Zukerman, Daniel Barenboim, Wynton Marsalis and the Three Tenors.

She also arranged for performances by many of the world’s foremost orchestras and dance companies, like the Alvin Ailey American Dance Theater and the Bolshoi Ballet.

Ms. Drucker was a tireless promoter and fund-raiser. She created and ran several different organizations, including the Great Artists Series and the Concert Association of Florida. She staged performances at the Adrienne Arsht Center for the Performing Arts in Miami, the New World Center, what is now the Jackie Gleason Theater in Miami Beach and the Broward Center for the Performing Arts in Fort Lauderdale. Though her operations’ finances were often precarious, she still delivered top performers, decade after decade.
