...raise $100,000 bail. He had just been sentenced to seven years in prison for his part in one of the most ingeniously bizarre stock swindles in modern history-after the longest criminal trial in U.S. Federal Court history (TIME, Feb. 22). The activities of Dardi's United Dye & Chemical Corp. cost some 3,000 small stockholders across the U.S. an estimated $5,000,000 and involved an improbable cast of Las Vegas gamblers, Wall Street respectables and well-known swindlers...
Despite the trial's tedious length, it took the jury only three days to return a verdict of guilty against three stockbrokers, a defunct brokerage firm, and a former head of the United Dye & Chemical Corp. All were accused of conspiring to swindle the public out of $5,000,000 through some elaborate manipulation of 500,000 shares of United Dye stock...
...Dyeing for the Empress. The company got its start 100 years ago through an ingenious stroke of applied science. Its founder, a German chemist named Eugen Lucius, perfected the first instant dye, which won wide popularity after a French silk dyer used it to dye green the silk to be used in an evening dress for Emperor Napoleon Ill's wife, Empress Eugenie. Soon researchers, using Hoechst dyes, learned that they could stain living and dead tissue to study the origin and spread of diseases. Famed Microbiologist Robert Koch used Hoechst dyes to discover the organisms causing anthrax...
This is the secret of Polacolor. The three superimposed images-blue, green and red-capture developer molecules with dyes of appropriate color attached to them. In spots on the film that have been exposed to blue light the silver halide grains in the top layer capture and hold all the yellow dye, which lies in the layer just below. Since no red or green light has reached this part of the film, the magenta and cyan dyes in the deeper layers are free to move to the surface. Acting together, they make a spot of blue...
...same molecular machinery produces the other colors. When green light from foliage forms a latent image on the green-sensitive layer, the magenta dye, which is nearest that layer, is captured. The other dyes, yellow and cyan, are free to go to the surface and become the green leaves in the finished picture. Similarly, yellow and magenta make red. Intermediate colors form at places where the images overlap weakly, allowing fractional amounts of dye to escape. White light in the picture (such as a cottony summer cloud) makes exposed spots on all three layers, capturing all the dyes and leaving...
