Crystal Chemical Company, ca. 1919 This building once housed the Crystal Chemical Company, a manufacturing space for pharmaceutical drugs and makeup. The company was originally located at 861 Westchester Avenue. Upon its founding, it made only three products. Within a year, it quickly expanded to twenty-eight, and moved to this much larger location. The new, bigger factory opened on September 18th, 1919, with a grand party, attended by prominent doctors, dentists, and retail distributors, who were given a tour of the six floors of the building. The building had facilities to store, distribute, label, and manufacture different medications and makeup. The makeup and beauty products especially were in high demand, due to their reduced price and an extensive marketing campaign; their slogan was "Crystal Products Satisfy."

Necker Undertaker Storefront, ca.1914. William Necker was born in New Jersey, and after leaving school at age 12, he worked his way up in the ranks at the Braumuller Piano Company in New York City. By the early 1890s, he was the head of the wood-working department. In the mid-1890s Necker changed careers and took a course at United States School of Embalming. Over the next two decades, he opened more than 20 offices in New Jersey and New York City, including this East 138th Street storefront. Necker died suddenly in 1916, and while the business did survive, most of the branches closed. Purchase of another funeral home business in 1948 resulted in the Necker-Sharpe Funeral Home, which the family sold to a former employee in 1958.

(Thomas E. O’Brien, 1924) NYC-HD, NR The Mott Haven Historic District also includes two notable civic buildings. Separated by two blocks and nearly two decades, both employ the stately Neoclassical architecture popularized by the City Beautiful movement of the early 20th century. More specifically, the buildings were meant to resemble Italian palazzi such as those found in Florence. They use a similar materials palette, with red brick façades and limestone trim, and Renaissance details such as molded window surrounds, round-arched openings, and quoins at the corners. The station house was designed by Thomas O’Brien, a Bronx resident and a lieutenant with the police department. He designed numerous similar stations throughout the city and was eventually named NYPD Superintendent of Buildings in 1929.

“Pulaski Park (Bronx): A view eastward across the park from the \[Willis Avenue Bridge]. On the extreme left is visible East 133rd Street, and on the right the approach to the bridge. The 3-story building within the park is that of the Board of Health. May 7, 1937.” In 1904, the City of New York acquired a plot of land in order to construct an approach (at right) to the Willis Avenue Bridge (opened 1901). In 1916, the unused land became a public park, later named for Casimir Pulaski, the Polish military commander who fought with the Continental Army in the Revolutionary War.

The Forum was built as a 2,700-seat vaudeville and movie house. After World War II, the struggling theater found new life as the Teatro de Puerto Rico, catering to The Bronx's growing Latin-American population. The theater featured acts such as Mexico's Cantinflas, Cuba's Tres Patines, romantic duos like the pianist Agustin Lara and the singer Libertad la Marque from Argentina, and Puerto Rican star Iris Chacon. Following a closure in the 1980s, the theatre re-opened as a performing arts venue and has been most recently used by a church congregation.

St. Jerome's Catholic Church was built in 1899-1900 to the designs of the architectural firm Delhi and Howard. The cost of the building was $100,000, a considerable sum for the turn of the 20th century. The Italianate / Baroque Revival building can house a crowd of more than 1400 parishioners. The church is a part of the Mott Haven Historic District, which was designated in 1969. The main thoroughfare of the district, Alexander Avenue (where the church sits on the corner with 138th Street) was once known as "Irish Fifth Avenue."

Willis Avenue Bridge, viewed from East Harlem, Manhattan, ca. 1934. The Willis Avenue bridge opened in 1901, connecting traffic from Manhattan's First Avenue to the Bronx and points north. The bridge was replaced by a new span in 2007. The bridge is also notable to veterans of the New York City Marathon: the bridge falls at the five-borough course's 20-mile mark.

St. Jerome’s Roman Catholic church complex occupies the whole eastern blockfront of Alexander Avenue between East 137th Street and East 138th Street and is dominated by the church’s corner tower with its colonnaded belfry and octagonal dome. The mostly Irish-American congregation of St. Jerome formed in 1869, and built the red-brick Victorian Gothic style school building at the southern end of the block first, in 1871, followed by the neo-Grec style rectory next door. The church itself was the last in the complex to be erected and was completed in 1898 in the Renaissance Revival style to the designs of the Manhattan-based firm Dehli & Howard. The church is an outstanding example of its style, with finely articulated facades of rusticated buff brick ornamented with robust Italian Renaissance-inspired architectural forms such as broken pediments, Ionic and Tuscan columns and elaborate cornices and entablatures. A statue of Jerome, the 4th-century scholar saint, sits at the corner of the church.

"Brown Place, south from but not including East 136th Street to its terminus at East 132nd Street. The two houses at the S.E. and S.W. corners of East 135th Street are in the process of being razed. May 11, 1937.” The buildings between 134th and 135th Streets were cleared for the construction of the Major Deegan Expressway, completed in 1939. At right is Public School 43, built in 1906. The school is named after the first recorded European settler of today’s Bronx, Jonas Bronck. Likely of Swedish origin, Bronck established his farm, “Emmaus,” in 1639, in the vicinity of today’s 132nd Street and Willis Avenue. The name ""Bronx"" evolved from the practice of naming surrounding natural features in relation to the farm (e.g. Bronck’s River).

Though the name of this business is advertised as plural bowling alley(s), further research suggests no other locations existed and the narrow width of the buildings makes it seem unlikely that this operation had more than one or two lanes.
