and, impressed by Leopold's work, in 1862, "the prince exhibited about 100 models of orchids and other exotic plants, which he displayed on two artificial tree trunks in his palace in Prague,"
which brought the skill of the Blaschkas to the attention of Professor
Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist and ornithologist. It was he who first requested Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museu ...
.
The director of the natural history museum in Dresden, Prof. Reichenbach, was enchanted by the botanical models and positive that Leopold held the key to ending his own inability to properly showcase marine invertebrates; in the 19th century the only practiced method of showcasing marine invertebrates was to take a live specimen and place it in a sealed jar of alcohol.
This killed the specimen, and due to time and their lack of hard parts, eventually rendered the specimens into little more than colorless floating blobs of jelly. The Dresden museum director desired specifically 3D colored models of marine invertebrates that were both lifelike and able to stand the test of time.
In 1863,
Reichenbach convinced and commissioned Leopold to produce twelve model

These marine models, hailed as "an artistic marvel in the field of science and a scientific marvel in the field of art,"
were a great improvement on previous methods of presenting such creatures: drawings, pressing, photographs and

or wax models.
Knowing this and thrilled with his newly acquired set of glass sea creatures, Reichenbach advised Leopold to drop his current and generations long family business of glass fancy goods and the like in favor of selling glass marine invertebrates to museums, aquaria, universities, and private collectors
- advice which prompted the swiftly and highly lucrative mail-order business that followed. Indeed, "the world had never seen anything quite like the beautiful, scientifically accurate Blaschka models"
and yet they were available via so common a means as via mail-order per one's local card catalog. Museums and universities began purchasing them en masse to put on display much as Prof. Reichenbach had - natural history museum directors across the world had the same issue showcasing marine invertebrates.
In short, Blaschkas Glass sea creature mail-order enterprise succeeded for two reasons: there was a huge and global demand, and they were the only and best glass artists capable of crafting literally scientifically flawless models. Initially the designs for these were based on drawings in books, but Leopold was soon able to use his earlier drawings to produce highly detailed models of other species,
and his reputation quickly spread; the task additionally furthering the training of his son and apprentice (and eventual successor), Rudolf Blaschka.
A year after the success of the glass sea anemones, the family moved to

. In 1886, the Blaschkas were approached by Goodale, who had come to Dresden for the sole purpose of finding them, with a request to make a series of glass botanical models for Harvard. Some reports claim that Goodale saw a few glass orchids in the room where they met, surviving from the work two decades earlier.
Leopold was unwilling: his current business of selling glass sea creatures was hugely successful but, eventually, he agreed to send test-models to the U.S. Though the items were badly damaged by U.S.

Goodale appreciated the fragmentary craftwork and showed them widely – convinced that Blaschka glass art was a more than worthy educational investment. His reasons for wanting the models was simple: At that time, Harvard was the global center of botanical study. As such, Goodale wanted the best, but the only used method was showcasing pressed and carefully labeled specimens — a methodology that offered a twofold problem: being pressed, the specimens were two-dimensional and tended to lose their color. Hence they were hardly the ideal teaching tools.
However, having already seen Harvard's recently procured glass marine invertebrates, Professor Goodale - like Professor Reichenbach before him - realized that glass flowers would solve his problem:
they were three-dimensional and would retain their color.
To cover the expensive enterprise, Goodale approached his former student
Mary Lee Ware
Mary Lee Ware, (Jan. 7, 1858 – Jan. 9, 1937) daughter of Elizabeth Cabot (Lee) Ware and Charles Eliot Ware, was born to a wealthy Bostonian family and, with her mother, was the principal sponsor of the Harvard Museum of Natural History's famou ...
and her mother
Elizabeth C. Ware; they were independently wealthy and already liberal benefactors of Harvard's botanical department.
Mary convinced her mother to agree to underwrite the consignment of the glass models that enchanted them both.
In 1887, the Blaschkas contracted to spend half-time producing the models for Harvard.
They continued to spend their remaining time making marine invertebrate models. However, in 1890, the Blaschkas insisted that it was impossible to craft the botanical models for half the year and the sea creatures the other half; "they said that they must give up either one or the other."

Prof. Goodale noted that the activity of the Blaschkas was "greatly increased by their exclusive devotion to a single line of work."
[Annual reports of the President and Treasurer of Harvard College 1890-1891, pp. 160-163 - https://iiif.lib.harvard.edu/manifests/view/drs:427018526$1i] In regards to Leopold's feelings for the Glass Flowers enterprise, and the change to it from the successful marine creature business, Goodale wrote the following in the ''Annual reports of the President and Treasurer of Harvard College 1890-1891'':
Production of Glass Flowers

Glass Flowers

, Mary Lee Ware engaged in correspondence with Professor Goodale regarding the making of the collection, one of which contained a remark of Leopold's regarding the false rumor that secret methods were used in the making of the Glass Flowers: "Many people think that we have some secret apparatus by which we can squeeze glass suddenly into these forms, but it is not so. We have tact. My son Rudolf has more than I have, because he is my son, and tact increases in every generation."
On this trend, he also once said that "One cannot hurry glass. It will take its own time. If we try to hasten it beyond its limits, it resists and no longer obeys us. We have to humor it."
The Blaschkas used a mixture of clear and coloured glass, sometimes supported with wire, to produce their models.
Many pieces were painted, this work being entirely given to Rudolf.
In order to represent plants which were not native to the Dresden area, the two studied the exotic plant collections at

and the U.S. to study additional plants, making extensive drawings and notes.
At this point the number of glass models sent annually to Harvard was approximately 120.
[Annual reports of the President and Treasurer of Harvard College 1890-1891, pp. 160-163 - https://iiif.lib.harvard.edu/manifests/view/drs:427018526$1i]
Rudolf made a second trip to the U.S. in 1895. While he was overseas - and eleven years into the project - Leopold died.
Rudolf continued to work alone, slowing down production so as to achieve higher levels of botanical perfection.
By the early twentieth century, he found that he was unable to buy glass of suitably high quality, and so started making his own.
This was confirmed by Mary Lee Ware during her 1908 visit to Rudolf in a letter she later wrote to the second director of the Botanical Museum, Professor
Oakes Ames

.
This letter appears to confirm the previous statement of Leopold's regarding his son; Miss Ware writes, "One change in the character of his work and, consequently in the time necessary to accomplish results since I was last here, is very noteworthy. At that time...he bought most of his glass and was just beginning to make some, and his finish was in paint. Now he himself makes a large part of the glass and all the enamels, which he powders to use as paint."
This missive to Professor Ames was published on January 9, 1961 by the

In addition to funding and visiting, Mary took an active role in the project's progress, going so far as to personally unpack each model
and making arrangements for Rudolph's fieldwork in the U.S. and Jamaica
– the purpose of such trips being to gather and study various plant specimens.
In 1911, Rudolf Blaschka married Frieda (whose maiden name is unknown) in a quiet wedding: "We had only a few guests but a great deal of people here had shown cordial interest...We took a four day wedding trip to visit the Ore mountains and the Zenkerhuette in Josefsthal a 200 year old glass factory where my great-grandfather was master about 130-150 years ago...we reached the remote place easily by the new railroad and we had right the last chance to see the interesting factory building. They are just going to pull it down and it will disappear". The couple hosted Mary L. Ware during the third of her three visits to Dresden, and they became very great friends.
In September 1923, Rudolf sent a letter to Mary stating that he had shipped four cases of specimens to the Museum in what was the first Glass Flowers shipment following

, but said that the complicated tax and inflation situation in Germany had left him without money and the Museum has not sent the 1923 payment yet. That November, he received $500 and a letter from Prof. Oakes Ames saying that Prof. Goodale had died that Ames was succeeding him, the money having been sent via Goodale's son Francis.
[Oakes Ames Correspondence: Botany Libraries, Archives of the Economic Botany Herbarium of Oakes Ames, Harvard University Herbaria] Ames was not as passionate about the Glass Flowers as his predecessor had been, seeing several unknown issues, but Ames soon requested what he referred to as "Economic Botany", asking Rudolf to make glass

, a request which Rudolf answered with alacrity and eventually evolved into a series of glass fruits in both rotting and edible condition.
However, Prof. Ames continued to exchange letters with Miss Ware discussing the project, namely the quality and speed of production as Rudolf ages, discussions which on Ames' part vary from controlled excitement to continued concern regarding the project and Rudolf's continuing ability to produce in a satisfactory manner.
Rudolf continued making models for Harvard until 1938. By then aged 80, he announced that he would retire.
Neither he nor his father had taken on an

, and Rudolf left no successor - he and Frieda Blaschka being childless.
For Harvard, Leopold and Rudolf made approximately 4,400 models, 780 showing species at life-size, with others showing magnified details; under 75% are, as of May 21, 2016, on display at the HMNH, (the exhibit itself dedicated to
Dr. Charles Eliot Ware, the father of Mary Ware and husband of Elizabeth Ware); the old exhibit contained 3000 models but this number was reduced for renovation purposes.
Unlike the Glass sea creatures – "a profitable global mail-order business"
– the Glass Flowers were commissioned solely for and are unique to Harvard.
Legacy
Over the course of their collected lives Leopold and Rudolf crafted as many as ten thousand glass marine invertebrate models and 4,400 botanical ones that are the more famous Glass Flowers.
