In 1907, my great-grandfather, Louis Windmuller, noted that the Dead Man's Curve problem had been solved at Union Square and the intersection of Broadway, Fifth Avenue, and 23rd Street had taken its place. His letter to the editor on the subject is on the left. To the right is an excerpt from the article which he references.
This photograph shows, at left, the "new" Dead Man's Curve on the southwest corner of Madison Park.
This detail of that photo is marked to show the street car lines, the Seward statue, and, by white arrows, the path Louis Windmuller would take, walking north on the east side of Broadway. You can see a traffic cop in the intersection and quite a bit of traffic (though not nearly as much at the early hour when this photo was taken as there would be at noon and beyond).
This photo shows Broadway and Fifth Avenue as they separate from one another and proceed northward away from the park. Louis Windmuller would take the sidewalk on the west side of the park and then walk up the east side of Fifth Avenue, stopping at the Reform Club on 27th if he wished (he was a founder and, as its treasurer, had bought the building at 2 East 27th) and then on to his "winter" home on 46th.
Taken 15 years earlier, this photo shows the intersection at bottom right, with the west side of the park at near left and, at far left, the passage of Fifth Avenue to the north.
This map shows Louis Windmuller's route from his office at 20 Reade Street to his winter home at 19 W. 46th, with the Reform Club, at 27th, in between. Both the 14th St. and 23rd St. Dead Man's Curves are shown in green. Windmuller was a famous walker. I've previously written about his walking, his office on Reade St., and his winter home on 46th. I've also previously written about the block that's outlined in red.
This is another view of the intersection, this time with the camera facing northwest. The photo was taken during a quiet moment in 1901 by William Henry Jackson, a well-known photographer working for the Detroit Publishing Co. (notice the three bicyclists, one of them a lady). The Fifth Avenue Hotel, at left, was owned by Amos Eno, a dry goods merchant who became a fabulously-wealthy real estate magnate. The Reform Club building on 27th had been Eno's home; was purchased from the estate at his death.
This photo shows the Dead Man's Curve at Union Square after electrification of the street cars. No one, including the lone (male) bicyclist, seems to be worried about the risk of injury.
This detail from a panorama photo shows the building owned by the Reform Club in 1911, just after the club had moved to new quarters in the financial district. The Club's address had been 2 East 27th Street, but the building is now identified as 233 Fifth Avenue.
This panorama photo shows the block on the east side of Fifth Avenue just north of Madison Square and just south of the Reform Club location.

"There would also be added danger at 'dead man's curve,' he went on, evidently under the impression that the curve was at Twenty-third Street. The term has been applied more generally at Fourteenth Street."

THE REFORM CLUB'S HOME.; PLANNING PLEASANT QUARTERS FOR ITS MANY MEMBERS, New York Times, April 18, 1890
IN THE REAL ESTATE FIELD, New York Times, March 18, 1910. "Reform Club Buys Building -- The Reform Club, through Louis Windmuller, Treasurer, purchased yesterday from the Cutting estate the building 9 South William Street, facing also on Mill Lane and extending through this lane to Stone Street. The building will be altered so that the club can use it as a midday luncheon club and for committee members to meet. Limited space will compel the club to restrict membership to a small number beyond the present roster."
A.R. ENO'S WILL PROBATED, It Disposes of an Estate Estimated at from $20,000,000 to $40,000,000. SMALL SHARE FOR SON JOHN C. All the Heirs Waive Citation and There Will Be No Contest -- Many Bequests Paid During the Testator's Lifetime Are Canceled New York Times, March 12, 1898. First para: "The will of Amos R. Eno was filed for probate with the Surrogate yesterday. Mrs. Antoinette E. Wood, a daughter of the testator, was the proponent, and in her petition she says that the value of the real estate and personalty is "not definitely known." The combined values are estimated to be between $20,000,000 and $40,000,000."
 The problem at Union Square had been solved by switching from cable-pulled to electric-powered cars.
 Eventually the City would decide that 14th Street should have an express stop; 23rd Street should not. Choate and Windmuller were acquaintances, probably friends. They served together on corporate boards (including the German-American Insurance Co.) and were walking companions, as evidenced by this article: NOTED CITIZENS OUT FOR WALKING RECORD, Gaynor, Choate, Hornblower, Parsons, and Windmuller Form the Pedestrians Club, New York Times, February 7, 1913
