This post shows why I keep my eyes open even after I’ve finished surveying the whole city. First, there’s always new stuff that was installed after I last came by. And second, sometimes I’d miss a mark, or find it indecipherable the first time. This was probably in the last category.
(For the couple weeks or so, I’ll be posting entries that I previously included on other pages, making sure they have their own page. Have to make things neat & tidy!)
Sidewalk maker: Nat Lena
16 November 2024Natale Lena (1885-1977) was born on a farm near Lucca, Italy, and came to America in 1902, arriving in the Bay area five years later. By then he knew enough about the concrete trade to get work in San Francisco. In 1908 he moved to Alameda and worked for the contractor Alexander LaPlant. He went solo in 1914, but a few “Lena & Helling Makers” stamps exist in Oakland from a collaboration with William G. Helling with dates of 1913 and 1915.
Merritt’s 1928 History of Alameda County states, “When he started in business for himself in Alameda he began in a small way. All concrete at that time was mixed on boards with a shovel, and a wheelbarrow was used to transport it to the concrete forms. The people of Alameda can well remember Nat Lena and his start in the cement contracting business but he laid a fine foundation for his future enterprise, and today he ranks as one of the largest and best known cement contractors in the Bay cities, while his equipment is modern and up to date in his line.” By the early 1930s his company operated from a compound in Oakland at 1174 19th Street, which still survives.
Nat and his wife Emma (1888-1954), who married in 1907, had no children. He was a member of the venerable Oakland Rotary Club for 46 years, and a Mason as well. Commenter Linda Hamilton recalled, “In 1978, following his death, Nat left $85,000 to the Club’s scholarship fund started with funds left by Sugar and Rice Manufacturer Al Saroni upon his death in 1961. By 2009, the Saroni-Lena Scholarship Fund provided one million dollars to over 600 Oakland teens to go to college.” And it’s still going strong.
Lena marks in Oakland run from 1920 to 1953. At first he used a racetrack-format stamp, though he would sometimes draw a mark by hand.
During 1934 he switched to an arched-text stamp with the name “Nat. Lena,” and he got a new stamp without the period after “Nat” in 1946.
Merritt’s history also notes, “He is one of the prominent members of the Cheese Rollers Club of San Francisco, an Italian organization, in which the members play a game similar to the American game of bowling, excepting that they use balls of cheese instead of wooden balls. Mr. Lena is an expert player and has won a number of prizes at this game.”
1933 – Ed Doty

I posted a 1933 Doty mark before, but this is a much better, standard version of his stamp.
Sidewalk maker: L. Scaramelli
14 November 2024
Livio Giovanni Scaramelli (1902–1969) was born in Lucca and emigrated from Italy at age five to Alameda with his mother Maria, joining his father Pietro who had emigrated five years before. He went by Lee John Scaramelli off and on during his life. He married Alma Ballwanz at age 22, at which time he worked as a welder. His father died in 1915 and in 1923 his mother married tile worker Antonio “Anthony” Falcier (1870–1949), another Italian immigrant, who trained Livio in his business, and in 1924 he appeared in the directory as a tilesetter. By 1926 he’d changed his listing to cement contractor and started to advertise in the papers. He moved a few times in Alameda, but from 1934 to 1949 he was at 815 Santa Clara Avenue before relocating to Walnut Creek. He advertised his services (for patios and floors) as late as 1957. He died in Carson City, Nevada.
In 1938 a newspaper puff piece said about him, “‘Lasting Satisfaction’ is his motto, and the only order he gives the five men working for him is: ‘The best is none too good.’ . . . [He] has the gold of kindness in his nature . . . is never a backslider in boosting the home town and would find friends even on Robinson Crusoe’s island.”

L. Scaramelli sidewalk stamps have dates from 1927 to 1954. In the 1940s he drew his dates by hand in a sure, elegant script.

They all have a period—“Scaramelli.”—at the end.
Sidewalk maker: Riechel & Bredhoff
9 November 2024From Frank C. Merritt’s History of Alameda County (1928):
“Cement has taken its rightful place high in the list of the leading building materials and is now practically indispensable in the construction of modern business blocks and residences. One of the leading cement contracting firms in the East Bay district is that of Riechel & Bredhoff. The senior member, Olaf Riechel [1877-1946], was born in Chicago, Illinois, February 21, 1878 [sic], and received his early education in the schools of that city. When twelve years of age he accompanied his parents on their removal to Alameda, California, and in the public schools of this city completed his studies. When seventeen years of age he went to work for Powell Brothers, with whom he learned the trade of cement working. He was promoted to the position of foreman and eventually became superintendent of construction, having in charge the erection of the Orpheum Theater building and other, important business structures, as well as large apartment houses and fine residences. He remained with that firm for twenty years and in 1918, formed a partnership with H[arold]. G[eorge]. Bredhoff, under the firm name of Riechel & Bredhoff, and engaged in the cement contracting business. They are doing a large business in their line, particularly as subcontractors, besides which they have laid many miles of cement walks and curbs in the East Bay cities. They did the cement work on the Heald Business College building, the Lynn building and the Barber block, as well as apartment houses and homes, and also erected the cement walls around the Pacific Gas and Electric plant on Thirty-first street, Oakland. They have likewise been very successful in building and selling homes.
“H. G. Bredhoff [1888-1975] was born in San Francisco, California, on the 8th of March, 1888, and received his educational training in the public schools of Alameda and Oakland. On leaving school he learned the trade of cement worker and was employed on the construction of the old Realty Syndicate building in Oakland. He was with Powell Brothers for sixteen years, leaving the employ of that firm to enter into business with Mr. Riechel. He is a member of the Fraternal Order of Eagles.”
Riechel was the son of German and Danish immigrants, and Bredhoff had German grandparents.
The firm operated out of 2509 Clement Avenue, Alameda.
Riechel & Bredhoff stamps appear on Oakland sidewalks with dates from 1921 to 1951. They have two forms that I call the high and low arch. The low arch is much less common, but both stamps have comparable age ranges. I didn’t differentiate them at first, so there’s still more research to do.
Sidewalk maker: F. C. Stolte
7 November 2024Ferdinand Charles Stolte (1889-1983), the son of German immigrants, was raised in Oakland and became a successful builder of high-end homes, apartments and commercial buildings in the area. He’s interred in the Mountain View Cemetery mausoleum with his wife, the former Elizabeth Moran of Crow’s Landing, and their son F. Charles Jr.
Merritt’s 1928 history of Alameda County reported, “He is painstaking in the fulfillment of his contracts, employs none but expert workmen and the work done by him has been uniformly satisfactory to those who have employed him.”
I have recorded a few dated Stolte marks ranging from 1931 to 1951.
